Good keyboard with 2 different tilt angles 4 and 8 degrees.
Mouse is wonderful with loads of extras great for my mac, variable speed scroller is good too.
They both can be paired to 3 devices and can be switched from one to another with single click of butto
I like the feel of the keys and when you get use to the curve of the keyboard it’s fine. The palm rest is fine and the material is comfortable. Nice that it automatically switches key position to match windows or iOS when you swap between devices.
My only gripe is, and hence 4 stars, the little rubber pads keep falling off. I work with a pc and an iPad Pro and it is so easy to switch between the two. The problem is i tend to slide the keyboard across the desk when switching between the ipad and pc to be in front of the screens. The little rubber feet are stuck on with double sided tape and they keep falling off. I may have to try supergluing them on.
All good up to three devices under control.. with the unifi dongle for non supported
I have 2 of these now. One is over 5 years old and is still going strong. I must admit that most of the letters have worn off the keys but it is still really nice and comfortable to use. Having just purchased a new one I can say that the bouce has also deteriorated over the time that I have had it. It is now my office keyboard and my nice new one is at home. The mouse is also great. This is will worth paying the extra for the quality.
I love the mouse in this set. It is ergonomic, responsive, and well built, unlike a lot of cheaper Logitech mice. The keyboard however is let down by the built in palm rest that feels like a strip of cotton stretched over a frame that you can feel when you rest your hands on it. Disappointing for such an expensive desktop set.
Keyboard feels sturdy, the keys feel nice, the mouse is also quite nice.
Holding down the 2/3 device keys on the keyboard activates pairing mode (Bluetooth) for them – had no problems pairing it to my laptop
ONE THING about the mouse that I’ve noticed in the reviews, and admittedly took a little while to figure out myself;
If your mouse wheel spins freely – The mouse wheel is Not broken, just click on the button above the mouse wheel to enable/disable the free spin.
Will be testing this thoroughly as a software enginee
I bought the keyboard and mouse combo because I need to connect between mac and pc. it works really well. Switching from one device to another is seamless. The M720 was fantastic. It take a day or two to get use to it. They keyboard unfortunately is less than satisfactory. I kept making mistake while typing on this keyboard. The key appear to be sink too deep for my short fingers and it appear to slightly slow to response in my case. So I was getting incorrect order of spelling. It probably need a little bit of time to get use to.
Overall, the mouse is good, the keyboard need a bit of time to get use too.
I love this product, the ability to switch between laptops etc is great. The only issue I have is that sometimes I get multiple repeats of the same letter, despite a single keystroke, not sure if this is a problem with the device or PC? Also I think for battery saving reasons it regularly reconnects of you pause the read a document etc, and this can delay progress a little . Overall I would recommend this produc
Mouse a little bit noisy while scrolling , than I expected, but reacts pretty well. Keyboard works good. I am not using it for gaming. Miss me alot prsc button.
I’m a product designer/educational writer for a health and wellbeing company. I use my computer every single day so I need something comfortable, good for general use, and wireless. I did a lot of research and settled on this. I usually only buy Logitech stuff because I know they are quality for the price.
The first keyboard had a faulty power button, but they replaced the keyboard and it came in two days as it has a two-year warranty.
My only complaint is that I wish the buttons did not rub off as quickly. For general use, you won’t notice for a good few years. But for me, I use the keyboard every single day and the buttons started wearing after about 9 months of use, but this is mild cosmetic wear, it did not impact performance.
The Logitech mouse that comes with the keyboard is brilliant. It’s basically a gaming mouse packaged up for office use, it’s the best mouse I’ve had. Just one complaint is that the mouse at this price point should be a soft click. The battery power however is said to last 2-3 years, incredible. I can confirm I used my last one for 9months and the batter power was still around 70% which I thought was incredible.
Overall, love the mouse and keyboard. When this breaks or wears out in the next however many years, I will probably just buy the next model. You can’t go wrong with this. I got it for 65 in a sale. But for me under 80 is a good deal.
With two PC’s to the same screen and limted desk space I got feb up switching around keyboards etc. This product solved that as switching.is now just a key press away. So my new set of keyboard and mouse is a winner.
I got my set to operate two PC’s neither of which has bluetooth so initally used the provided receiver on one and a usb bluetooth addition on the other. The problem with the bluetooth is you can’t boot up and enter the BIOS on boot up because the bluetooth is not active immediately!
Then I noticed the receiver it came with was a unifying type (not a special bluetooth device as first thought) and so I dug out a spare logitech unifying receiver and paired the keyboard and mouse with that instead of bluetooth – you need to use the ordinary unifying software to pair extras not the software that comes with suppied receiver. Once paired with the extra receiver, it can even be moved to any other PC that does not have the unfying software. So it works on my dual boot PC and happy in windows XP as well.
End result both PC’s can have immediate use of the gear and can enter BIOS if you need to on boot up. Simply switching between the computers by using the 1,2,3 special keys on the keyboard and selecting the 1,2or3 on the mouse.
Bottom line is connections can be either Bluetooth or unifying receiver or a mix of both!
I may end up using the 3 switch to use this great set on a smart TV as well as the two PC’s
I like: The seamless ability to switch from work laptop to my PC without moving the unifier around each time. I like the mouse, which is well made and has two scrolling modes.
I don’t like: The keyboard is a little small, and the “wrist rest” does not feel adequate (thick) enough to support your wrists. The keyboard feels cheap to me. Okay for work but not great for gaming. I personally would like quieter keystrokes too. Still, I am coming from a Microsoft Comfort Keyboard which was amazing to use and had a great wrist support, but the mouse started to die and the keyboard was probably going to be next (both were 15 years old!) so it was time to change things.
So my conclusion….if you frequently PC game, as well as work from home – i would probably go with the new microsoft comfort curve option. However, if you don’t game and have a laptop/pc and work from home and want the minimum fuss and ease of use, then this would be perfect.
4/5, loses 1 star because of the small, not very comfortable keyboard.
Bought this as I have a multiple devices and pcs at my desk that I swap between frequently. Works really well apart from intermittent issues with my MacBook Pro. When connected to the MacBook Pro via Bluetooth the connection tends to drop and then reconnect after a second or so, sometimes when waking the mac from sleep mode it won’t connect to the mouse. Other than that works really well with windows devices
This is a good keyboard and mouse set that I’ve now been using for 1.5 years.
The keyboard is comfortable to type on, although I do find the keys a little loud.
The mouse wheel has a nice feature where you can either lock it so it moves in steps or have it free-wheel, as per your preference – a nice touch!
But, I have one big problem with the mouse – the position of the forward/back and Easy-Switch buttons. For me, the forward/back buttons are set too far forward, such that I need to adjust my hand to use them – a real PITA for gaming! Where I’d expect to find the back/forward buttons, is the Easy-Switch button – this means I press it accidentally on occasion, suddenly losing keyboard/mouse input and wondering why! *Really* annoying when gaming!
If Logitech provided a means to disable Easy-Switch (I don’t need it), this would be a 5-star review – but they don’t, despite installing their crappy, bloated, data-slurping Logitech Options software :-/
This has saved me putting away the other keyboards/mice when not in use. Switching from pc to work computer is so much easier (1 set for all). Very nice. One of my best buys.
Tengo una pantalla que conecto a un PC windows y a un porttil MAc. Ahora puedo manejarlo todo con un nico teclado y ratn.
El cambio entre ordenadores es super fcil y adems el teclado est adaptado a Windows y al Mac,y parece tener la calidad que se le presupe a logitech.
I got this set for home office back in November and was excited, as I normally really like Logitech products.
The mouse is great but the keyboard … well let’s say it’s putting a lot of strain on my marriage and potentially threatening my living condition.
1st time I started using it I though it was a time machine because that clicking of the keys took me Steiger back to 1995. The clicking of the keystrokes is so loud that my neighbours have asked if there is a wood packer and/or if we are having constant works being done.
My spouse started wearing ear buds and threatening to leave if I don’t get a new one, due to the noice level.
So my veredicto is:
Mouse is great, ergonomic of the keyboard is great, but the noice level of the keystrokes is fatal.
Beide funktionieren gut und lassen sich schnell umschalten. Leider ist die Funktion der mittleren Taste unter dem Rad nirgendwo beschrieben, man muss es selber rausfinden.
Wenn mann mehrere Rechner hat und die ber einen Monitor mit gemeinsamer Maus und Tastatur betreiben mchte ist das die perfekte Lsung. Ein Laptop und ein Desktop PC an einen 32″ Monitor mit der Logitech Maus & Tastatur funktioniert wunderbar und das Umschalten ist ganz einfach. Einziger Mangel es gibt keine separaten Lautstrketasten sonden man muss ber die Funktionstaste gehen.
First impressions (UK keyboard) after a month of daily use.
Tested on Windows not on Mac.
Documentation, a bit sparse.
Great arty web pages selling us the ‘sizzle’ of product X less about the nitty-gritty.
Set up – had to install the Options software on my Windows 10 before I could get mouse or keyboard to work.
But perhaps that was user error.
Keyboard
no off switch – it is annoying that have to pull out the batteries when pairing you mouse and keyboard with the easy-switch software or when travelling.
very slight hump in the middle of the keys (ergonomic), but not enough to be off putting or noticeable in use.
Sturdy keyboard, no wobble on the desk or flexing while typing.
Folding 2 front legs give you options for 2 different height apart from flat.
Slightly softer plastic keys, not hard & shiny.
has caps lock light as expected
no num lock light (but software can put num lock/caps lock on the screen for a couple of seconds)
windows & mac keys – cons lots of symbols crowded on some keys e.g. @ and #
You loose 3 keys: print screen, scroll lock and pause/break (replaced by easy-switch keys)
mouse seems a delight
mouse moves smoothly on desk. Has an off switch.
No lag so far. (has this on the M310 mouse).
I don’t use the full features of the mouse. Don’t use any artistic software to heavily test it.
Batteries – can use standard rechargeables, so no worrying about the lifetime of a built in battery.
Switching between machines on one keyboard.
This was the killer feature for me.
I have a locked down work laptop (Win 7) and a Windows 10 machine.
More Logitech docs on what is possible would be helpful.
I work on both throughout the day, so this saves desk space and me switching to another keyboard/mouse.
Using the Easy-Switch key on the Keyboard and Mouse I can switch to the other device.
I was pleased this still worked on an old locked down Windows 7 machine.
I cannot install the Logitech Options software on this machine but that does not affect switching.
However it is not perfect. When I want to switch machine I have to switch both the keyboard and mouse e.g. press the 1 key on the keyboard and the one key on the mouse.
There is no option to press the keyboard or mouse key only and automatically switch the other mouse/keyboard -why?
The mouse only has one button to switch so you have keep pressing the button until the relevant number is lit up.
Connectivity
You get one USB Receiver. I have 2 older USB Receivers from older Logitech wireless keyboards.
You can also use the Bluetooth on your laptops but I have not tried this.
I leave the 2 USB receivers in my two machines to enable the easy-switch.
Tolles Produkt.
Es lst die technischen Herausforderungen perfekt, mehrere Gerte zu bedienen. Auf Knopfdruck lsst sich von einem PC auf den anderen wechseln. Sogar das automatische Wechseln beim Split Screen Modus wird untersttzt. Das was die Software meines LG Displays eigentlich schon knnen sollte, aber nicht kann, lst das Gert mit Leichtigkeit.
Im Einsatz seit Monaten ohne einmal zu laden.
Die Handauflage ist weich und aus einer Art Gummi, leider recht schmutzanfllig.
Ein top Produkt!
Set acquistato per uso lavorativo, workstation per CAD: mi ci sto trovando molto bene.
Tastiera usata anche in combinazione con Vertical Mouse Logiteh, con lo stesso ricevitore.
Mouse usato anche con laptop, sia con ricevitore USB che con Bluetooth.
Funzione Flow interessante e funzionale per gestire fino a tre computer collegati alla stessa rete contemporaneamente, con una sola tastiera e mouse senza dover usare i tasti di selezione: raramente il passaggio da un terminale all’altro si blocca, ma probabilmente a causa del collegamento di due mouse.
When my old Microsoft Natural Ergonomic 4000 keyboard died after 14 years of faithful service I spent quite some time looking at options for its successor. At the moment I am working from home, like many fortunate enough to be in a position to do that, and I am constantly switching between 3 different devices – 2 work laptops and my own.
I choose this to simplify my keyboard-hopping life and it has been perfect for this. The Logitech Flow feature, which requires installing the Logitech Options software on each device, allows me to simply move my mouse off one edge of a screen and it appears on the corresponding edge of the screen of a completely different computer. It can optionally switch both keyboard and mouse or just mouse, and using the button selectors I can override the active system on one or both devices so the keyboard is controlling one computer and the mouse another. It works seemlessly with Mac and Windows, and using the Logitech USB receiver and Bluetooth on different devices.
I find the keyboard comfortable and tactile to type on, perhaps a little noisier than I expected but it is far from the clackety-clack of the old IBM Model-M keyboards. The mouse is also comfortable but is handed, so if you like to use your mouse with your left hand you might be less happy.
I am very happy and impressed with the set. It is an expensive option, but if it lasts as a long as my previous keyboard then I view it as a worthwhile investment.
One problem I have found is that the function keys do not have spaces between each group of four, so evey time I go to press F5 or F8 (two keys that are used regularly in my particular line of work), I often end up missing because my fingers expect to feel a gap either before or after.
Regarding the mouse, I’m happy that this one is a good size. It’s getting more and more difficult to get one that isn’t too small that isn’t designed for gamers. I don’t have particularly big hands but most mice that come in office sets are tiny and uncomfortable. This one is perfect and has enough buttons to be productive without being overly complicated.
Build quality is up to the usual Logi standard and will hopefully last a good while, given the relatively high price of this set, although I’m not entirely sure that the soft touch wrist rest won’t wear out first.
I would have given this 4.5 stars if I could because of the function keys, but I’ll leave 5 because otherwise it’s a really nice keyboard and mouse.

Bin ganz begeistert von dieser Kombination. Das USB-Empfangsteil steckt bei mir in einem USB-Umschalter fr einen 2.Rechner. Zuvor die Funktastatur Logitech EX 110 im Einsatz. Die bentigte Ihren relativ groen Funkempfnger fr die Signale. Dieser wiederum per USB-Kabel verbunden mit dem Umschalter. Batterien fr Tastatur und Maus wurden gefressen da permanent aktiv – auch bei ausgeschalteten Rechnern. Jetzt ist das anders. Trotzdem praktisch kein Verzgerung nach Einschalten von einem der Rechner. Dazu die Ergonomie beider Teile. Einfach eine Freude.
Tastatur und Maus funktionieren, sind ergonomisch und man kann mehrere Rechner mit einer Tastatur/Maus verbinden.
Ein Punkt abgezogen da kein Handbuch beiliegt und auch nicht als Download nicht zu finden ist.
Auf Antwort vom Support dazu warte ich jetzt schon fast 2 Wochen.
La souris est facile d’utilisation (droitier), le clavier galement. appairage facile avec plusieurs ordinateurs, ce qui vite de changer de claviers/souris chaque fois.
Conforme aux attentes.
A noter, clavier un peu “bomb” et surlev, avec un support pour les poignets.
The keyboard and mouse came in good packaging, with batteries included (one AA for the mouse, and two AAA for the keyboard). The keyboard is in UK English layout (that is the one I ordered).
Please read through below and consider your own purpose and preferences. Some of what I consider an advantage may not be seen as so from a different point of view.
I use the mouse and keyboard for general typing and for programming. I use Windows and Mac (not tested for mac yet). I have had this product for 3 days now.
Advantages:
– Keyboard has a full numpad and functionality buttons (ins, del, home, end, page up, page dn).
– Keyboard has an indicator for when the Caps lock button is on.
– Keyboard buttons are firm and do have a smooth “press” feel to them. The keys are not shallow (like laptop keys), but rather sink in when you press them. (I see this an advantage, you may not).
– The keyboard has 3 buttons that are dedicated to switch between 3 devices. I have not used this functionality yet, but definitely useful as I use a work computer and 2 personal computers.
– The mouse has a button (next to your thumb) dedicated to switch between devices. Each time you click the button, it switches to another device. It also shows you if you are connected to device 1, 2 or 3 via illuminating numbers on the mouse.
– The mouse is slightly large in size and is comfortable to use. I prefer large mice than smaller ones. Only larger devices I have used before are technical ergonomic mice that are ordered specially.
– The mouse click does have a sound and feel. I see this as an advantage. Unlike other mice that are extra smooth and do not make any sound or have minimal click response.
– The mouse has 3 customizable buttons (next to your thumb rest) that you can use for almost anything! this is a great functionality that was not in the product description (at least I did not see it). I have set one to copy and the other to paste. I have always been looking for a way to copy/paste simply with the mouse (like in Linux). It is very easy to customize and change the mouse settings using the software (installs automatically on Windows 10).
Disadvantages:
– No indicator for when Num lock is on.
– The keyboard is about 45cm X 15cm. The width is slightly big (not too much). In order to use keyboard and mouse, my mouse arm needs to be away from my body (slightly less ergonomic).
– No automatic power saving option that is available in other keyboard and mouse sets.
To consider:
– The keyboard has a rest pad at the bottom (as seen in the photos). You may or may not like this.
– The scroll of the mouse is like a wheel. Unlike other mice (that I am used to) that rotate in discrete manner and stop. This scroll rotates like a free wheel continuously until you stop it (think of spinning the wheel of a toy car).
Overall, a very good set I would recommend. I had bought a set last week (around 20) and decided to replace immediately with this one.
This is a great piece of kit for me personally, I use my computer for gaming and media, largely from my sofa or dining table, and the mouse works on any surface I put it on without tracking problems. The ability to reassign mouse buttons through the Logitech application has come in very handy for general volume control (my audio output was lagging when I used the HDMI to TV cable as a source, but changing to PC speaker output lost me the ability to remotely adjust volume. Changing the function of the side buttons on the mouse solved this for me) as well as for different functions on specific games. I’m not a fan of the middle wheel button as it has too many functions too close together to reliably click the right one mid game, but again this can be remedied by switching to a different button. Overall I’d say this set solved all the problems I needed it to without me realising it would even do so before I bought it. The Bluetooth function is useful for freeing up USB ports although because my Bluetooth adapter is also my wireless card it does cause lag when I’m downloading a lot so I’m not currently using it. A dedicated internal Bluetooth adapter would probably solve this issue.
Kit preso usato arrivato puntuale e in ottime condizioni.
A mio parere la bombatura nel mezzo non mi sembra comodissima perch sono sempre stato abituato a tastiere piatte.
Il poggia polsi comodo ma avrei preferito fosse pi rialzato.
Tasto centrale della rotellina troppo duro. Alcune vole schiaccio quelli laterali.
Nel complesso un buon prodotto per la cifra pagata.
Da ich auf der Suche nach einem neuen Set war, wurde ich auf diese aufmerksam. Positiv ist, dass es eine Ablage fr die Handballen gibt und die Maus sowie Tastatur ber Funk ist. Fr den Preis ist das alles super, nur die Maus knnte unserer Meinung nach beim klicken ein bisschen leiser sein.
Forse mi sarebbe piaciuta ancora pi silenziosa, ma nel complesso ha tutto ci che cercavo in una tastiera di questo tipo.
Spie che indicano il blocco maiuscole, messaggio a schermo per indicare attivazione e disattivazione del blocco maiuscole e numeri, utile, anche se io lo uso poco, il fatto di poter comandare pi dispositivi. Il mouse lo adoro, soprattutto per la possibilit dello scorrimento infinito (quasi 😉 ) della rotella che accelera non poco lo scorrimento delle pagine senza usare il cursore laterale. Molto ergonomico (solo per destrorsi) ed il notevole peso che da stabilit, viene compensato dai pattini (teflon?) che lo fanno scorrere molto bene.
La ricomprerei
A full sized keyboard with decent spring loaded keys. I purchased this at a discounted price and whilst I use it most days, I don’t think it warrants it’s high price. Keys are a bit noisy, especially the space bar. As a touch typist at approx 100 words a minute, I find this keyboard a bit clunky and the keys a little high for me which makes the wrist support on the keyboard pretty useless. Sadly a US layout but full sized. Having a specific on/off switch is good and prevents keyboard from connecting accidentally and draining battery life. Blue tooth connectivity is good and having the ability to switch between 3 devices whilst continuing to type is really useful. Keeps up with my speed of typing without many errors. Mouse works well too. Overall, a decent full size keyboard suitable for typists. Just amazes me every time that I use it at how over priced it is. Still, figure I’m getting my money’s worth (eventually!)
Overall this is a nice keyboard and mouse set for working from home. I like Logitech products generally and this one fulfilled my expectations in most ways. A big plus point is the unifying receiver which is easy to set up and allows me to transition between my home and work setup (both Logitech) very easily.
The reason for a loss of one star are the keyboard shortcuts. They are not obvious at all, so finding where the Windows key is, how to take a screenshot on a multi-monitor setup etc. was a bit of a pain. My Logitech keyboard at work is a lot more obvious/simpler than this one.
Here’s some shortcuts to help if you get stuck:
Fn + Alt + Insert – Single Screenshot on Multi Monitor Setup
Fn + Insert – Screenshot (if multi-monitor will capture all screens in one)
Start is equal to the Windows Key – so Start + Left Arrow will push an active screen to left side (right arrow for right side, up arrow to maximise)
Como punto en contra dir que la almohadilla de tela que tiene es algo sucia, hubiera elegido un tejido ms sufrido.
No he probado la opcin de conectar a otros equipos, pero la verdad que fue uno de los motivos que me hizo decantarme por este modelo.
Original Review
I would recommend this keyboard and mouse combo for daily general use depending on your workflow, I would not say it is the best if you use keyboard shortcuts extensively or for programing (probably not good for gaming either). I love the ability to connect to three machines and save desk clutter – this is the main selling feature and it works well and is a far cleaner solution than the KVM switches of the past.
The Keyboard is well shaped, ergonomic and has soft feel keys. You can tilt the keyboard using the usual wee flip out legs on the bottom – Logitech has put two sets of these, one for four degrees and the other for eighth degree – nice!
I usually go for the MX ‘Cherry Red’ clickity-clack keyboards and usually find the louder they are the more I like them, however, I like the feel of the K850 – it is quiet but the keys depress far enough (6mm maybe) to feel ‘positive’. I am not a touch typist but almost – I find this keyboard takes my eyes away from the screen more than it should due to lack of grouping of/spacing between ancillary keys, it lacks tactile feedback.
This is a full size keyboard, however, the layout has a slightly ‘compact’ feel to it. The main QWERTY keys are fine but the control keys are not. The function keys have no space between F4 and F5 nor between F7 and F8. I like having F keys in groups of 4 with space between the groups. In similar fashion the ESC key is hard against the F1 key. Further, there is very little physical separation between the number row and the F-key row. In practice, I have to actively look for F5 rather than using peripheral vision/muscle memory or tactile feedback to just find it. The ESC key also suffers the same problem, it is crowded. Other keys that, in my opinion, are too crowded and too small are Shift, Cntrl, Fn and Alt on the left side of the board.
In general, this keyboard does not make it easy to find ancillary keys by feel. This does make coding or using keyboard driven complex apps slightly more difficult to use and I would imagine gamers would find this problematic too. I’m quite old school I use keyboard shortcuts extensively and prefer this to using a mouse. However, this layout may suit most users better.
The other negative is the key printing (see photo). Logitech have tried to make this keyboard OS agnostic – or rather include key labels for both windows and mac, the result is not pleasing at all. So rather than having the “Win” key you have a key labeled ‘Start’ in bold white, a horizontal line and then ‘Alt’ in a grey colour. It’s a bit busy but the main keys are cleanly labeled. This does not bother me too much but I imagine it would make finding the pipe or tilde key difficult for less confident PC users. Perhaps this is aimed at users who will connect to a windows and a rain mac/other machine?
The wrist support is a soft rubbery type fabric, it feels nice but is an absolute dirt magnet. No One likes a dirty keyboard but we all hate cleaning nooks and crannies so I would not buy this for a teenage boy… This is a poor choice of material in my opinion. The fabric seems designed to trap dirt, it won’t just wipe away but gets ingrained into the fabric itself. This will become a big annoyance for me as the KB ages.
The Mouse is very good. It has three thumb buttons for forward and back and device selection. I do wish they had separated the forward back buttons from the device select button slightly or made the device selector feel different. It works on a shiny surface but I do notice it is smoother on a proper mouse mat. I’m not too fussy about mice as long as they have a scroll wheel, forward thumb key, back thumb switch and center mouse button. This mouse has all of these plus horizontal scroll.
The thumb wheel is good and includes tilt (horizontal scroll). The wheel has two modes, free wheeling for rapid scroll down long documents and a ratchet setting for more precise scrolling – the button behind the wheel selects this. It feels nice in hand and encourages a good arm/hand/finger position. However, the center click are not very easy to use without accidentally ‘scrolling’. Probably not a good mouse if you are into CAD.
Other than that the mouse feels precise but is also zippy. I use two wide monitors (about 4500 pixels) and can go to screen edges and over to the other machine (see below) without running out of mouse mat. The acceleration algorithm is really good, I am quite happy with the default settings but it is configurable in software (and most OS’s…).
Multi-Device Support
You can pair the KeyB/Mousey combo to 3 devices via Bluetooth or the (1 included) unifying receiver (tiny wee usb dongle). You can use the unifying receiver one one machine and Bluetooth on others or all bluetooth or all unifying receivers (only one included). It just works and just works very well. Once setup, you just press one of the numbered white buttons to select the device and pair to that device – you have to do this on KB and Mouse which is annoying but this also allows you to be mousing on one PC while ‘boarding’ on another (should you care to do that, why I do not know).
Software
Logitech Options is the software suit which allows you to adjust mouse and keyboard settings, key assignments (per application), mouse speed etc – it is a reboot of ‘Setpoint’. You can also install advanced features such as ‘Flow’ (move mouse from one PC to another). I installed Options, got annoyed because it wants to connect to ‘the cloud’ and then discovered a conflict between Options and my own custom software (to allocate keys etc) – my audio volume became uncontrollable so I uninstalled Options.
I tried ‘Flow’ briefly but found it to be more of a dribble than a steady flow, perhaps my mouse has prostate problems? To be fair, my setup is a bit complex and my main PC probably has old copies of Setpoint and other trash that conflicted with Flow. I need to reinstall this PC and maybe try again. There is good support on the Logitech website and people seem to like it but I did not persist with Flow – there are better alternatives.
In general, I dislike Logitech’s software and find it works best when uninstalled;) Modern operating systems are more than capable of using all the standard features without adding bloated control apps. While it allows you to customise the combo I find there is no *useful* function that can be achieved within applications or by small third party utilities. I must say, ‘Options’ is optional, it’s not needed to use the combo with multiple devices.
Alternative to ‘Flow’ [MS Mouse Without Borders, Windows only]
If you have a need to move the mouse/kb between Windows machines then you should search for “Microsoft Garage Mouse without Borders”. This is a MS app that essentially shares any mouse/KB between all (Windows) PC’s. I have two Win 10 boxes on my desk. Number 1 has the Logitech KB/Mouse connected via Bluetooth while the second machine has an old wired KB/mousie – I can use either mouse on either machine (and also share clipboard etc) just by travelling the mouse over (KB follows mouse). As the Logitech is only paired with one machine I can still connect it to two other devices!
So, my setup with regard this product is as follows. I use Mouse without Borders to share KB/Mice both ways between my two Windows 10 boxes – this is only one of the three connections. Device Two is a Linux box. Device Three is a Tablet (using BT). The Bluetooth setup was seamless. Switching between devices is flawless and very satisfying.
Recommended?
Yes, it does work very well. it is built well and any problems with Logitech’s software are most likely easy solvable and options to Options exist. I will probably look for another fuller ‘full sized’ keyboard with better tactile feedback for my coding/CAD/Photoshop machine and consign this KB/Mouse to my ‘office’ machine and for tablets etc.
Just one more Inch!
Had this just been an inch bigger and the ancillary keys spaced better … sometimes an inch really does make all the difference!
**Superbly engineered, the keys almost do the typing for you, a light touch is all that is required.
**Supremely comfortable, with a lovely almost imperceptible curve ad camber that takes half a day to get used to, but you then realize how un-ergonomic all other keyboards are.
**I thought I’d miss the backlight (my previous keyboard being a K800, which died after a splash of lager or two upset it) but you don’t, that’s a battery life-killing gimmick anyway. Do you want to write or stare at the pretty lighting on your keyboard?!
**It works out of the box, instantly, just remove the battery saver, plug the dongle thingy in and go. I found it worked perfectly and instantly with both my Macbook Pro and Windows 7 Pro Desktop PC.
THERE IS JUST ONE ANNOYING DOWNSIDE… and here is is. I bought this to flip between aforementioned Macbook and PC, so I can do two jobs at once, both badly. No such thing as multitasking is there? Anyone who tells you there is, is not to be trusted.
Guess what? It only comes with one bloody receiver.
Ah ha! I have TWO spares from the K800 (keyboard and mouse came with one each) does this Keyboard talk to either of the K800 receivers though? Does it buggery.
I guess if one of my devices had Bluetooth it wouldn’t have been an issue, but they don’t so it is. Another 9.99 order for another dongle it is then.
Otherwise, I love it and will try hard not to spill lager beer on it.
I use this as a daily driver in my office after being bored of multiple keyboards and mice taking up too much space. Got it connected to a desktop, my surface pro and my phone though the latter isn’t the most useful if I’m honest.
Switching between devices is a doddle and the desktop switching button on the side of the mouse is a nice touch. The logitech software that allows you to map different actions to buttons is straight forward to use and allowed me to set things up quickly, it’s also not essential as it works fine straight out the box.
The mouse is comfortable, a good size and feel with all buttons easy to access – even the device switching one at the back. It moves freely over the desk without a mouse mat and has a decent enough level of accuracy for work but I’ve not used it for any gaming. Lastly for the mouse it has lateral scrolling on the mouse wheel! Love that feature on a mouse though I appreciate it is probably not relevant for everyone.
As for the keyboard it’s comfortable and rest at a nice height with the legs all the way out, the typing experience is ok but it isn’t as good as a mechanical keyboard. That being said the ergonomic aspect feels good and I can overlook my preference for mechanical keyboards in favour for it being wireless and supporting multiple devices.
I think it’s useful for a specific use case, not for people who only want it to control 1 device. If you have multiple machines though this is great.
This keyboard and mouse can pair via Bluetooth or Unifying receiver to up to 3 devices. Then swapping between paired devices is as simple as pressing one the white keys numbered 1-3, and clicking a button on the side of the mouse to cycle between 1, 2 and 3. The combo comes with a single Unifying receiver. I put this receiver into my home desktop, I paired to my laptop using Bluetooth and my work laptop using a Unifying receiver I have with my older Performance MX mouse (approx 2014). The pairing process was smooth and seamless for the more modern machines. I did try to use Bluetooth for the work laptop but the one I had at the time was older with Window 7 and did not support the enhanced bluetooth needed for these devices. I have a new work laptop now so could try bluetooth with that but it works great with the receiver still in it so I’m going to leave it alone. For the windows 7 machine which had the Setpoint software on it, I had to go into the Unifying software to pair the mouse and keyboard. I had trouble with this the first attempt but it worked fine the next time I tried. However there is a workaround using the unifying receiver if you have trouble pairing with a particular machine, which is to plug the receiver into a different machine, and pair to that using the Options software, then just plug it back in the original machine!
The work laptop with its unifying receiver is also still paired with this older mouse that I keep in the laptop case. So when I’m at work I switch on that mouse and it works perfectly as it did. When I’m at home I leave that mouse in the bag and click the device button on the new mouse. It all works very smoothly.
If you use the new Logitech Options software (replacement for the older Setpoint software) on all your devices you can configure something called Flow which will seamlessly switch mouse and keyboard between your devices as you move your mouse cursor off one screen onto the other! I haven’t tried that yet as I don’t have admin rights to my work laptop so I can’t install Options on that. Note that you don’t need Options to use these peripherals.
The keyboard in this set is the K850. I don’t know if this can be purchased separately. It has a better more positive action than the MX 5500. With that, many keys would stick a little if you strike them at the corner. This does not happen with the K850 When new it feels quite “rubbery”, a very damped travel, and is very quiet. In use however this loosens up considerably and gives the feel similar to many other keyboards of reasonable quality, together with the usual slightly clacky noise you get from most keyboards that get heavy use. It’s not a particularly noisy keyboard by any means, but it is a big contrast between new and virtually silent and worn in. It has a traditional key layout with all the function, control and cursor keys in the “right place” for a UK keyboard. The “windows key” is labelled the start key as it has a different function on a mac. The keys with different function or mapping on a mac are labelled such, with a line separating their displayed mac function from the windows function. The keyboard has two tilt angles from the folding support legs, 3 if you count “flat” with the legs folded away, which I use. The main keyboard area has a slight curve for ergonomic reasons but to me it just feels like a comfortable “normal keyboard” in use rather than a special ergo one that would need getting used to. The fixed palm shelf is some sort of soft touch textured rubber with a woven fabric texture. It feels nice but I’m sure it will trap dust and debris and will not be easy to clean.
The mouse is labelled the M720 and can be purchased separately as the “Triathlon M720”. This is a much less sculpted affair than past mice like the MX Revolution, and a bit smaller. It is clearly designed for right handed users but while not ambi, I think left handers could use it without it feeling too awkard. The issue for left handers would be the button placement. It has two programmable thumb buttons which default to browser forward and back. The button behind these is the device switcher. The free spinning (“Hyperfast scrolling”) scroll wheel functions like most mouse wheels as a “third button” if you click down on it, and supports side scrolling if you tip the wheel left or right. Behind this is the mechanical switch button to toggle between free spinning and click to click function on the scroll wheel. Gone is the software controlled function of the MX Revolution but you gain the standard third button function in return.
I can’t comment much on battery life as I’ve only owned it for 4 weeks now but the manufacturer claims 24 and 36 month life from the mouse and keyboard respectively, from the non-rechargable batteries supplied. 2 x AAA for keyboard and 1 x AA in the mouse. The Options software still reports battery full for both. Certainly far better than the 2-3 weeks of heavy use from the rechargeable Performance MX and the 4-5 weeks from the MX Revolution.
In summary I’m extremely happy with this purchase. I wouldn’t have bought either separately without the multi-device capability but even without that capability, the keyboard is the best I’ve owned and the mouse is about as good as the Performance MX.
Die Verarbeitung fhlt sich sehr gut an. Die Tastatur ist sehr leise, doch nur im ersten Monat. Danach wird sie lauter und lockerer (abhngig davon wie viel man sie verwendet). Der Bluetooth Adapter sollte eher nher an Tastatur und Maus sein, sonst ist die Verbindung nicht konstant gut. Logitech Software sehr einfach und praktisch gestaltet. Das Feature, dass die Tastatur mit bis zu drei verschiedenen Gerte verbunden sein kann, ist sehr praktisch.
Die Tastatur ist sehr zu empfehlen, hat aber noch Verbesserungspotenzial.
Die erste Tastatur die nahtlos beide Welten verbindet und dabei sowohl Mac OS (inkl. Gesten) wie auch Windows bedient. Die Tasten fr Strg, Alt wie auch Cmd und Alt sind sauber verteilt und es macht Spass damit zu arbeiten. Da ich viel mit Remote Desktop (TeamViewer, Citrix, Hyper-V, VMWare) arbeite waren vorher fr jede Remote-Lsung eigene Tastenkombinationen besonders fr Copy&Paste anzuwenden. Das ist hier deutlich besser.
Ein Punkt Abzug fr die noch etwas schwergngigen Tasten, die nicht gleich zurckspringen sondern gedmpft den Fingern folgen. Dies ist etwas gewhnungsbedrftig.
