I researched mouse types for tennis elbow and this one has really helped reduce the pain I feel from typing by changing my hand position to a more natural one when using the mouse.
This is a great mouse. I spend a lot of time at my computer at work and I had noticed that I was getting lots of pain in my hand. This mouse really helps with that!
Having to get used to double clicking with my hand at a different angle but otherwise I like the mouse. It feels natural and comfortable. It worked straight away when I plugged the dongle into my laptop. Its really lightweight which I discovered when I knocked it off the table but it still worked fine luckily!
Love this mouse, very impressed, nice design and shaped well for my tiny hands. It sometimes runs away from my hand a bit, so sometimes hard to get a hold of, but once it is in your grip it is great.
My chiropractor recommended I try one of these mice as had consistent shoulder pain, since using for around 3 weeks the shoulder pain has completely gone! Amazing. The noise itself is easy to use and get accustomed to, only issue is sometimes it loses its tracking and requires a quick switch off/on, but otherwise great produc
This is the best office product I have bought for myself! It may take some getting used to but in the end you will be glad you use it. I used to get major pain from twisting my wrist in pain using the standard mouse but this one gave me no pain whatsoever. Would definitely recommend
I developed RSI from using a traditional mouse constantly for work. This has really helped as it’s light and easy to use, with the positioning just right for my hand. The design is good and it’s a trusted brand. I have two of these now – one for home and one for the office. The battery lasts a long time.
This is the second ergonomic mouse I’ve used and they honestly do stop the pain I was having before. fully recommend
I like this mouse a lot as it fits my hand perfectly. But over the last couple of weeks, it has started to freeze and the red light is always flashing. I have replaced the batteries three times with brand-new ones. I still have the same problems. It’s very disappointing.
Anker arrange a replacement for me and the new mouse arrived today. I wish all Retailers were as good at solving problems as Anker.
okay but too large for my hands so personally does not work for intended purpose
I thought it worked on my glass-topped table which a lot of optical mice have trouble with (I have a Logitech laser mouse which works fine), but it turned out to not – so you will need a mouse pad if you want to use this on glass. However for the price you really can’t complain – friends who previously have had wrist pain swear by these so I am giving it a go!
Comfortable hand position feels more natural and pain free. It is for the larger handed or those with long fingers as it is quite big.
Bug bear of it is that batteries don’t last long I have changed batteries twice in the short time I have had it approx 2 months. I will admit that I don’t turn it off when I’m done working so it could be that.
I’ve had two of these – one lasted ages but then I bought another based on liking the original so much but was disappointed when it stopped working after a couple of months. The seller has been in touch and has replaced the mouse with a new one – great customer service, thank you.
I didn’t realise how much a standard mouse was uncomfortable having used one all my life. This is a game changer and soo much more comfortable!
Game changer. Why does the standard design of mice still exist? This is great for the wrist. I am a long-time sufferer of Carpal Tunnel syndrome and have had treatment but it comes and goes with the amount of admin and typing I do. So this helps my symptoms not worsen. I can sleep at night in less pain due to this.
My wife is disabled and has restricted use of her hand – using a normal mouse is very painful for her, this is perfect and requires little change to her normal hand posture. You almost hold it like a cup and you can use it and the buttons with very little effort.
I bought it as a Christmas present and only just changed the batteries yesterday (4 months use).
It was easy to pair, super responsive and changing the batteries is super easy (for me). Any negatives? Not really.
Good quality and price, does the job, and improves user comfort.
Not using it for either of these for working environme
Arrived within estimated date and packaged well. Mouse works well for general use.
Couple of things to note, if you are thinking of getting one.
Size matters
If you have tiny hands or especially short fingers, you might find this mouse a bit too big, and it slides away when you try to grab hold of it. There are mini mice that might suit you better.
Getting used to it
Using an upright mouse takes a little bit of getting used to, but it won’t take long. I’d say after a couple of days of using it, I was no longer aware that it was a funny shape, and I was using it as easily as a traditional mouse.
Higher profile
If I have one criticism about these mice, it is that their profile is higher than traditional mice (ie they stick up instead of lying flat), so when I reach for it without looking, I do have a tendency to knock it to the floor sometimes. I am getting used to it, so I’m sure this will pass!
Traditional versus ergonomic
Now that I have been using this mouse for a few weeks, I can’t imagine ever going back to the flat ones.
I work on a computer all day and I was starting to get some wrist pain on my right hand.
My work colleagues suggested an ergonomic mouse and I decided to try this one. It felt very odd the first few days as the way you move your cursor with this is different. Now that I am used to it, I don’t even notice it and definitely, it helped. I no longer have wrist pain.
It works on a mouse mat, which my regular mouse does not.
The AAA batteries it needs seem to last about 3 months, but make sure to have some at hand as I didn’t see any warning of being low when they died on me.
The Bluetooth connection seems to work fine and in 4 months I have been using it, I think I only had to turn it off and on once or twice to make the connection work. That could be the mouse or the laptop’s fault.
There is a switch to increase or decrease the sensitivity/speed of the cursor. I don’t fiddle with it.
I am pleased with it and I would recommend it. To me, this is another good product from Anker. I tend to go for their products as I find them dependable.
I’ve had issues with my wrist for more than twenty years now, and using traditional mouses has lately become a problem. So I bought this Anker mouse hoping it would be better for my wrist.
Overall, I like it since I don’t have to twist my wrist so much as before. But it doesn’t mean it’s perfect. The first thing I noticed is how light the mouse is, which is perhaps a good thing for some, but not for me. I’ve lifted it off the mouse pad more than once during work by accident because it’s so light. Having attachable weights at the bottom, as some gaming mouses have, would add the option to adjust the weight better.
My second issue is that the max DPI is too low for my taste. I’m used to much higher to limit the necessary movement of my wrist to get the pointer where I want it to go.
For now, I’m giving the Anker mouse a chance for a few more weeks. The mouse’s weight issue could just be a matter of adjusting my working habits, but the DPI issue could be worse to adapt to overall.
I purchased this mouse to use on my company laptop. I have had to use an Ergo mouse for a few years now after in excess of 20 years in the IT industry using a standard mouse took it’s toll and started to cause incredible RSI pain in my hand and forearm.
The mouse I was issued by my company was wired and it had three mouse buttons, It was a very frustrating item to use often the cable would catch on something on my desk and pull the mouse away just enough to cause pressure on the third button whihc could result in a closed window, lost email and it was driving me mad.
I didn’t want to spend a fortune on a mouse to use at work and the Anker product stood out on Amazon with good reviews.
I liked the fact it only had 2 buttons and it was similar in shape to the wired mouse I was using so would not feel awkward or alien to use.
The item came next day and was packaged in a very nice presentation box (something I have experienced with other Anker products I have purchased in the past.
I received last Thursday, installed 2 x AAA batteries and set it up.
It’s really comfortable and I love the freedom of movement without the annoyance of the wired connection my old mouse had.
The mouse pointer speed was a bit high but after some adjustment it is now perfect for me.
The build quality is very good as you would expect from Anker, though the dongle doesn’t clip into the base of the mouse, it just pushed in, I am not sure how it is held into position and I am not sure how well it would be gripped in there while in transit so I will probably leave it plugged into the USB port on my laptop.
It’s really comfortable to grip and move and I like the soft touch feel of the surface.
Yet to learn how long the batteries will last as I have only used it for a dy and half so far but I guess if I remember to turn it off at the end of the day the batteries should last a long time.
So all in all I’m impressed with this mouse, it’s not massively expensive and has a very good look and feel to it.
Enough digressing…
I have a two-monitor setup (1x 27 inch, 1x 24 inch) side by side, so do a lot of scooting of the mouse from one end of the screens to the other, so need something fast but accurate. This mouse seems to achieve that surprisingly well.
Being a vertical mouse, it’s easy, when holding the mouse, to nudge it slightly when clicking a button. But if I consciously squeeze it a little with my thumb as I press the button, it works fine. I guess my muscle memory will very quickly learn to do this.
Anyway, if I remember, I’ll update this review in a few weeks of use to let anyone who’s interested know how I’m getting on with it.
Let’s start with the good things:
– Surprisingly comfortable even with a big hand, but cutting it close
– Nice feeling textures. Doesn’t feel cheap or plasticy
– Good durability despite the low cost
– Button Locations (including back buttons) are comfortable and easy to reach
– Allows for DPI Switching (more below)
– Wireless
Cons. And this is where you need to make the decision for yourself whenever or not this is a deal breaker for you
– The Optical Sensor is questionable. With various surfaces, or even a grainy gaming-style mousepad, it has noticeable issues to pick up and a stutter is the consequence. Even on smooth surfaces and “standard” mouse pads it didn’t pick up as fluidenly as I’d expect for a mouse in the modern age. The issue persisted regardless of DPI Setting.
– No onboard memory. DPI Settings are stored on your Computer. While you can change the DPI Settings, you can only do that once the USB Dongle is in the PC, and the Mouse is properly recognized. Pressing the DPI Switcher Button without that will just default you to the default setting. This is a potential issue for any locked (work) devices that do not allow for dongle installations
– No charging possibilities. 2 AAA Batteries are needed. If this is a pro or con for you I’ll let you decide, for me it’s a definite con.
– To pick up from my Pro List. While I have big hands, they do fit into the mouse. But barely. Any non perfect positioning and I am sliding over the surface. With a bit more training I’m sure I’ll just get used to that, but a larger size would be appreciated.
I bought this for work after having ZeleSouris at home for two-three years. I can say I prefer the ZeleSouris because I think it provides better ergonomics than the Anker.
Pros:
-Very good build quality
-Cheaper than ZeleSouris
-Generally good mouse
Cons:
– The buttons are too hard to press. I noticed it even before plugging in the usb dongle for the first time. This causes strain mainly on the index finger after a while. My advice to Anker is to make the buttons as lighter to press. Also, they should move the button clicker (micro switch) a little to the back and to allow the button to be pressed not only by the finger tip but also using the middle part which is the joint between the proximal and intermediate phalanges. This is possible with the ZeleSouris Ii have. Maybe a person with bigger hands could do it on the Anker, too.
-The forward button is placed greatly inconvenient. Again, the ZeleSouris is better and has it below the thumb. The Anker has it in front of the backwards button and above the thumb which makes it hard to press without lifting you thumb from the mouse (so you don’t press the backwards instead).
-The scroll wheel mouse is very hard to press using the index finger. It’s easy using the middle finger though. But sometimes I prefer to use the index finger.
-General finger position is more open than “clenched” which I think is the more natural position. Open position and clicking in open position causes more strain.
-Not as vertical as the ZeleSouris
I focus on the cons here but besides them it is a very good mouse. It could be great for someone with bigger hands or with not as tender tendons as mine so I give it 4 stars.
After many, many clicks my old Logitech M560 mouse was getting tired, and I was finding that it sometimes took more than one click to achieve an action. That basically means that I’d worn out the micro switch and that it was time for a new mouse. Friends had told me about their new upright mice and given favourable feedback so I decided to try one for myself, although I was reluctant to spend a lot of money on one. This Anker model seemed to fit the bill, and I knew from experience that it was a good, reliable brand.
Maybe I should have looked more closely before buying it but this mouse isn’t fully upright design that I was expecting. Instead of my hand being fully upright it’s at an angle of around 45 degrees which is halfway between upright and a traditional mouse. It does feel more of a comfortable position than my old mouse but I’m now wondering whether a fully upright model might have been better.
I have big hands (size XL with gloves) and fit that the size of the mouse is okay, although the back/forward buttons aren’t ideally placed for me — they would suit medium to large hands better. In many ways it does feel quite natural to hold and use, and it took me no time at all to get used to the positions of the left/right click buttons. However, I’ve noticed an issue when I click the left button in particular — the action of pressing it means that the mouse naturally tries to move further away as I push, and sometimes that means that the switch doesn’t actually operate. The only way to counteract that is to push with my thumb at the same time as I press with my finger, and that doesn’t feel comfortable or natural.
I’ve stuck with using this mouse and things have improved as I got even more familiar with it. The mouse itself is pretty good, especially for the low price compared with the Logitech models. I’ve been using it for many months and found it to be very good despite the flaws mentioned above. Anyone else contemplating a move to this sort of mouse could do a lot worse than to choose this one.
I was tempted to buy a straight out replacement for the Microsoft Ergonomic Mouse (26.99 at the time of this review) but saw this option which not only had higher ratings but was cheaper and had a few other features I liked the look of.
So how does it stack up against the more expensive Microsoft option?
+++++++++++ THE GOOD ++++++++++
1 – THE PRICE – At 11.99 (at the time of this review) this mouse is a steal for the functionality it offers. I know you can pick up wireless mice for next to nothing these days, but for a speciality product like this, I am impressed.
2 – STEEP ANGLE – The angle of the mouse is steeper than the Microsoft version. It makes for a more comfortable wrist position.
3 – BUTTON FEEL – The Microsoft mouse had some much lower profile buttons which might look better, but aesthetics isn’t everything. The buttons on this mouse are always easy to find and being as they are good old fashioned click buttons, I have a suspicion that there’s less to go wrong with them.
4 – SHAPE – One thing I really like about this one is the way that it is shaped. It fits in your hand as though it was moulded for it (which it probably was) and it just feels like the right way to hold a mouse.
5 – WIRELESS ADAPTOR – The Wireless adaptor is not only easy to use, but it’s low profile. This means that when you have it in your laptop on your lap it’s not going to get in the way.
6 – EXTRA BUTTONS – This isn’t technically better than the Microsoft Sculpt, but it is definitely worth mentioning. The extra two buttons for the thumb are really useful. I have a mac so with an app like ‘Better Touch Tool’ you can easily reprogram those buttons to do some really useful things. It’s handy.
– – – – – – – – – – – THE BAD – – – – – – – – – –
1 – NO BATTERIES – Okay, it’s no biggie but it does frustrate me. You can bet 12 AAA batteries for a pound in Poundland these days. That’s just over 8p per battery. Would it have killed them to spend 16p or to stick 2 AAA batteries in the pack and save me having to take a trip into town when I realised I didn’t have any in the house?
2 – A LITTLE TOO THIN – Again, this is only a small complaint, but this is just a little too thin. It puts just a little more pressure on your thumb to grip it than it would had the mouse been a little thicker. This is easily rectified by resting your thumb on the top of the mouse, but I thought it was something worth mentioning.
3 – HAND DOESN’T REST ON IT – This is the only real drawback I see from using this mouse over the Microsoft version. The Microsoft mouse has a rounded design that allows your hand to rest on top of it. this takes all the pressure off your wrist completely. With this device, your hand doesn’t so much rest on it as lean against it. Again, it’s something that isn’t going to make a big difference, but it is a slight draw back.
========== THE VERDICT ===========
Overall, I am really impressed with this mouse. If it was the same prices as the Microsoft mouse, I might have to give the Microsoft one the slight edge for the simple fact that it fits in your hand just that little bit more comfortably and the side to side controls on the scroll wheel, but it would be a really close call. The better buttons on this mouse and that nicely sculpted shape brings it really close for me.
Considering it is much cheaper (more than half the price) this is definitely a good buy and I am not disappointed to have bought this mouse over the Microsoft one. I’ve saved 15 (minimum) and feel like the few problems I have with it will go away as I get used to this mouse.
It’s an easy 4-stars for this one. I highly recommend it.
Well… This mouse definitely requires some getting used to. I’ve been using it for a couple of weeks now and I think I’ve given it a fair amount of time. So – the pros first:
+ The upright position definitely feels more natural and less straining
+ It’s big enough so my pinkie doesn’t feel squashed out alone – it rests together with all my other fingers
+ Seems well built, works straight out of the box, didn’t have to install any crapware
And the cons:
– I tend to stiffen my thumb when I left-click which is somewhat tiring, but not a huge problem.
– The thumb position is kinda low for me, I’d prefer it to be a little higher, where the left-side buttons currently are. Maybe just leave more thumb space to accomodate different people’s preferences.
– Movement accuracy is still a problem, and it’s nothing to do with the mouse itself – just the different position it’s held. I’ve been trying to play Diablo for a while and it’s still not as easy as with an ordinary mouse. It’s fine for browsing though, and most of my daily work doesn’t require playing games, so…
– Seems to turn itself off too quickly – 5 minutes maybe, I haven’t timed it. Then you have to click to activate it, just moving it doesn’t work.
– The USB transmitter slot on the bottom is a little too tight, you really need to work your nails to get it back out of there.
Now, the cons may be more, but that’s just because I’m listing everything I could think of. The accuracy thing might just require more time, I’ve had 20 years of practice with a regular mouse… But if you hope to use the mouse for gaming, watch out for this. And it will be worse with shooters! I don’t even want to try Counter Strike with it yet. But for office work it should be just fine.
Another thing which is neither a pro nor a con – I had to start scrolling with my middle finger because it feels more natural. This is another of those things which feels straining at first but then you forget about it.
So the bottom line is – might work for you, but don’t expect miracles and be patient, you need to get used to it.
I love Anker products, I feel they generally make a great quality product, a beautiful design, and most importantly it does what it says on the tin.
So while browsing one day I came across this vertical mouse I had a quick read and thought it would be a nice mouse to carry with my laptop, especially with its RSI preventive ergonomic design. (I unfortunately already suffer from carpel tunnel/RSI in my left wrist so I want to minimise the risk to my right wrist.
Throughout my many years I have used trackpads (don’t really like them), trackballs they are alright and standard mice. Yes I have usually gone for gaming Razer mice with extra buttons and a nice adjustable. However I thought for my laptop this vertical one might be a nice change, and also when out with clients maybe showing them something they didn’t know existed.

The Review
I got home from work to open a parcel with the mouse in it. It was in a clear plastic box, showing the full style of the mouse, with a full information card at the back. Reasonably good minimalistic packaging.
I opened it all up and plugged the dongle into my Windows 7 laptop and it installed in seconds The longest part was me having to go find 2x AAA batteries for the mouse.
The mouse itself has an On/Off switch which is good for transporting so the mouse keeps the battery use to a minimum, rather than thinking it is active when loose in your bag.
My laptop table by my sofa is one of the Black Tempered Glass tables, I was expecting to have to go hunt a mouse mat as when I used my standard optical mouse on it, it doesn’t work. I thought I’d give this a try before getting up and trying to find a mouse mat and it worked perfectly. No stuttering, no jumping, no inaccurate control, it was fantastic. (As a side note, throughout the night with cats and kids knocking me around, the mouse was used on the surface of; a black leather sofa, a teenage mutant ninja turtle fabric PJ trousers and the cover of a glossy magazine and all the time it worked perfectly.)
The mouse felt natural to use, not quite like a joystick, but not like a mouse, but sort of in between, with a angle that made my arm feel rested. The photos of muscle/bone twisting from normal mouse usage clearly made sense now.
WristAngles
The buttons are ideally placed for use by your fingers and the scroll wheel is easily accessed too, just like on a regular mouse.
Going from typing to mouse I find is easier, it is like your hand just slots into a natural position with the vertical mouse rather than having to pounce upon a regular mouse to take control.
The only thing that concerned me after this quick embrace with this new style mouse was how accurate it was. When I am creating visual basic interfaces and am moving items by pixels with the mouse, I need a good accuracy. Track pads have never offered this, but a normal mouse and track balls have been good So I immediately launched into a product to see how I would get on with this new mouse, and I have to say there was no difference. This were just as easy to move around accurately, it just felt more comfy to use.
Occasionally it does feel a bit weird to have your hand slightly upwards when using this mouse, but I think that’s just due to nearly 30 years of regular mouse usage, after 24 hours I’m more than happy to have this as my laptop mouse. Yes my main desktop will still use my Razer Naga mouse, but that’s because I have so many functions for work and games mapped I don’t want to lose them.
I bought this mouse because using an ordinary mouse has given me a lot of trouble with my upper arm and shoulder. The problem with a standard optical mouse is the very fine movements that need to be made in moving the whole mouse. I was fine in the days when they had a ball underneath because I used to turn the mouse sideways and work the ball with my left hand. I’ve tried trackball mice but they always seem too big or are not compatible with sharing between two hands.
16/12/13
It arrived on 16th December. The first thing – I found the packaging hard to open with an arm problem! Also a little disappointed that no batteries were included. My first impression was that it’s a nice design but feels a little bit bulky, a little bit tall so my hand doesn’t rest on the mouse mat and feel I need a wrist rest, though all the buttons seem to lie reasonably under my hand. The left button is a bit stiffer than I’m used to.
To give some idea of my hand size – If I put one end of a ruler in the angle between thumb & first finger, the measurement between the angle and the tip of my middle finger is 13cm
18/12/13
I feel my fingers have to be a bit straighter than they would really like, and forced a bit far away from the thumb. It still feels a bit large and clumsy, though it’s actually no more clumsy than any mouse.
20/12/13
I feel the joint at the base of the 1st finger is getting pushed into an unnaturally acute angle and this is slightly straining it. I still have to use my shoulder to move the pointer, and think I might do better with a trackball if I can find one that suits me. Today I finally just went back to the ordinary mouse, which felt like a relief. The Anker one still feels too bulky. I have to say that it seems to be extremely well made and a well thought-out design, but just not right for my particular problem.
30/12/13
I now have a tablet, and I think a touch screen is probably the best answer for me as it avoids the need for a mouse altogether.
So why am I giving it 5 stars?
Because, although it’s just not quite right for my particular problem, if a sideways mouse is what would suit you, then this one is very good value for money, extremely well made, a nice design, works straight out of the box and I like the extra buttons. But that is not all. Anker’s aftersales care goes far beyond what you might expect. Two weeks after my purchase I received an email from them asking how I was getting on. I replied with most of the text above and their response was overwhelmingly caring, including giving me a full refund even though the fault was not theirs. So I think one could buy from them with complete confidence.
The near-vertical design definitely reduces/overcomes the pain that a “normal” mouse grip can cause – it’s a more natural hand/arm position. The matte finish is comfortable and makes the mouse easy to grip, and the sculpted shape means it fits naturally in the hand (right-handers only!). The left/right click and scroll wheel are well placed and easy to operate. For my hand (average sized male hand, I think) the mouse feels very slightly too small, but it’s not uncomfortable.
Sensor performance is excellent. It works well on my shiny black wooden desk surface without a mouse mat (previous mice have been very confused by it). Resolution can be adjusted to one of 3 different settings, but I found it hard to tell the difference – movement resolution was good even at the lowest setting.
It doesn’t come with any drivers. On Mac OS X this means the left/right click and scroll wheel work fine, but the 2 thumb buttons and scroll wheel button do nothing. I installed SteerMouse to overcome this – it allows me to programme those 3 buttons and use them for different actions in different applications. Very handy. But it does add 13 to the overall cost. USBOverdrive would probably also work with it.
The only ergonomic issue is that the two thumb buttons are poorly placed: I found it difficult to operate them without changing my grip on the mouse, and often when I squeeze a thumb button, my finger also presses one of the left/right click buttons on the other side.
Others have complained the mouse goes to sleep and has to be switched off and on again to bring it back to life. They obviously didn’t bother to read the brief instructions that come with it! It does indeed sleep after about 8 mins. A click on any of the buttons wakes it up again instantly. Once you get used to that it’s not a problem at all.
Overall, I’m very happy with the mouse, especially considering the excellent price. I haven’t had any reliability problems so far (a few weeks).
