Posturite Penguin Ambidextrous Wireless Ergonomic Mouse | Rechargeable, Alleviates RSI, Easy-Glide, Vertical Design, PC Computer & Apple Mac Compatible (Black/Silver, Size: Large)

certainly improved the tension/spasms in my shoulder/ neck muscles and did not take too long getting to use to it on the PC with either hand. easy to install. Sometimes I press the wheel instead but this is only a minor point and I have to think a little more. However I do wish I had bought it a long time ago so its gets 5 stars

I have been using this mouse for some weeks at the time of writing. I suffer from some RSI related tendon discomfort from mouse clicking with my middle and fore fingers of my left hand. I tend, with a normal mouse, to flex the whole of my finger from the 3rd knuckle (the one closed to the wrist at the base of my fingers). This mouse has completely eliminated the associated discomfort that I feel in the tendons that control the flexing from the knuckle. It does this by promoting a finger position that encourages the curling of the finger to press the buttons, rather than flexing at one joint. The curling action uses a different set of muscles and tendons and allows the resting of the other tensions and muscles that are the problem. The rest really works as I have been able to use a normal mouse for a day without problems when I have forgetton to pack the penguin. In addition it holds your hand in a neutral position that is good ergonomically. It is a wonderfully designed product and I couldn’t go back to a normal mouse now.

Takes some getting used to for sure but has made a world of difference to the pain I was getting in my hand from a mac mouse I got used to it quickly and has a great battery life!

I had been given the mouse for my work, so was glad of the opportunity to buy one for my home. It bery comfortable and easy to use.

I bought the Large wireless for my husband after he had tried and discarded many other ergonomic mice. None of those worked. He is 6′-4″ with long fingers and most mice did not allow him to grip them without bending his fingers in some way to click or scroll. As he works on a computer for 40 hours or more a week, he needed something that would eliminate the pain he had endured for years. This mouse has done that.
No, this mouse is not going to feel right until you get used to it, and it WILL take a while because it is not like any other mouse we have used or seen. But after the first week he wouldn’t trade it for any other mouse.
Battery life is excellent, it lasts more than a week on a full charge.
In the 16 months he has been using this he has never had a single time when the mouse lost its connection with the computer.
Never had any issue adjusting mouse speed or sensitivity. Using it on both Windows 7 and 10 machines from HP and Dell.

This may look phallic, but who cares? It’s also a conversation starter. I bought this in hopes of reducing carpal tunnel symptoms. Not only reduced, but eliminated! It took about a week to get used to using this, but now I can fly across 2 screens and improved my work efficiency.

4 1/2 YEARS LATER…This is one product that I will fully support. Since I began using this, I have had no symptoms of carpal tunnel. After heavy, daily use at work over the past 4 1/2 years, the main button is finally starting to fail. I came back to this because I am going to order another one. A product this helpful lasting over 4 years is worth the investment, in my opinion.

Edit October ’21
I reordered the one the lasted me 4 1/2 years, but after only 2 months, the wheel failed and was causing my cursor to jump all over the screen. I ordered a 3rd one, thinking that I may have just gotten a dud. This time I bought the extended warranty. Again, same thing after 2 months. I tried to file a warranty claim at a local “participating claims center” as contained within the warranty documentation. What a headache, and was going to cost me money to have it sent out. Forget it, I just bought a different brand and type of ergonomic mouse, since this product clearly isn’t what it used to be.

I’ve had one of these at the office for a couple of years and all discomfort from prolonged mouse use went away completely once I switched to this mouse. Now buying one for home. Great product.

J’ai presque fini de gurir mon picondylite (Tennis Elbow) en employant cette souris durant les deux dernires semaines au bureau (8 heures par jour).

Cela prend 1 journe ou 2 pour s’habituer mais a vaut vraiment la peine.

Conseil: Placer la souris de faon a avoir votre bras le plus prs du corps possible. J’ai donc achet un clavier sans pav numrique pour que le clavier et la souris soit vraiment devant moi et que je n’ai pas travailler le bras tir.

Was recommended this product after having a workplace assessment and have bought additional for home use since. Takes a little bit of getting used to initially but I find much more comfortable than a traditional mouse.

Bought to try and address a pain in my right hand, this mouse is pretty neat in that you can use it left or right handed. I followed the size guide before buying, even printing off the PDF and matching my hand against the printed picture. This led to me buying the large sized version which I feel is just a little too big – despite my hands measuring comfortably over the “large” indicator line by a good 2cm. So I would advise caution when sizing your hand as it feels like it’s a bit larger than it should be. That said, it could be part of the design but it does feel a little awkward.

The wireless version comes with a relatively smal USB dongle that the device automatically connects to pretty quickly and it’s immediately recognised by Windows as a standard mouse needing no additional drivers. The dongle will protrude from the side of your laptop quite a bit – fortunately there’s a little covered reces in the base of the mouse to house the USB dongle when in transit.

The mouse has a horizontal scroll wheel and two buttons – these are the active controls that you will use. Sitting underneath your little finger is a switch that changes position when you use the mouse right vs left handed, this effecively reverses the direction of the scrollwheel. It may sound odd but it makes perfect sense when you’re using it.

The mouse also has a number of resolution settings, which can be altered by pressing a button on the underneath of the unit. This has been a really useful feature for me – if yo’uve never used a vertical mouse before and, especially if you’re using your “wrong” hand, then having a super-sensitive mouse is the last thing you need. So i started with it on a relatively low sensitivity meaning I had to move the mouse a large distance to cover one side of the screen to the other. As I got more used to useing the new mouse (and the wrong hand) I was able to turn up the sensitivity, improving my productivity without being really frustrated from the outset.

The battery lasts a really long time. A USB charging cable is supplied, and here’s my only gripe – rather than using micro USB or USB-C, they’ve used a proprietary charging port so if you lose the cable you’re in trouble. Battery charge is indicated by an LED behing the “penguin/spine” logo on the unit. So far mine has lasted about a month without needing a recharge.

It’s missing some of the other buttons that I’d come to rely on with my prevous mouse (A logitech Performance MX), like the back button for browsing etc. BUt that’s not the end of the world. What’s more important is that it has helped me to use my other hand, relieving pressure on my main hand which had started to suffer from the early signs of RSI.

So if you’re looking to prevent or manage RSI, this is a great mouse. Particularly if you’re prone to moving your mouse by flexing your wrist but not moving your arm. This kind of movement can put a lot of strain on your hand – the penguin mouse makes this impossible by resting the heel of your hand on a platform at the base of the mouse itself. The only way you can move it is to move your whole arm, significantly relieving the pressure from your usual mousing style. It’s got a few quirks but RSI is something you’d really rather not have, so even though it seems expensive, it’s cheap consider the problems it can help prevent.

Fits right in my 8″ long hand. Won’t change back to a regular mouse.

FAST shipment, packaged properly, item is just as shown – Many Thanks!

Taking me a while to adjusts, but no more shoulder or hand or wrist pains, so it is good for me.

This “mouse” is indeed quite strange. it is kind of like holding the control stick on a helicopter (or jet, picture the movies) and them moving it around to have the cursor move. I bought one for myself, and the same exact thing for my dad (as he was complaining his carpel tunnel was acting up).

I have used mione for weeks now and am totally used to it. I bought the other “Popular” sideways mouse (the evoluent brand) ns did not like that one nearly as much. I bought “one of each” figuring I would use one on my ‘main’ household PC (kitchen) and use the other at my desk (which is still not setup) and this penguin mouse won the test (IMO). I just found the Evoluent mounse to be to easy to “Click” something when I was trying to move it around.

I like the shape of this mouse. I like the way my whole hand rests on the mouse, making it easy to move. I would give this product a lot of “stars” IF…
It’s a good thing the power switch is on the bottom and easily accessible, because I sure do use it a lot. The mouse simply stops working frequently (usually several times an hour) and I have to shut the mouse off and turn it back on. And then it works for a bit. The resolution button – the same thing. The resolution will change for no reason. And the pointer will frequently jump to the top of the screen. Or to the extreme right.
I will confess I still use this mouse. After using a standard mouse at work all day, I like using a mouse with a dramatically different hand position. But the extremely poor software/driver ruins this promising product.
And I contacted the company to see if they could help. Never heard back…
My advise – don’t buy this.
Several weeks later…
I again contacted the company after I posted this review. I did hear back this time, and a very helpful customer representative arranged for another mouse to be sent to me. Unfortunately, the replacement mouse has the same problems. It’s possible this could be a computer/mouse incompatibility problem – not all reviews mention this problem and it’s impossible to ignore. And, yes, I’m still using this mouse. So maybe you will be lucky and this mouse will play well with others in your set-up. Wish it did with mine…
But wait, there’s more!
A week or so after receiving the second mouse, the customer service rep told me that they had done some tinkering with the mouse’s innards and they would be sending me the new model. Well, third time is the charm – this one works perfectly! I can wholeheartedly recommend this mouse! This mouse solves the problem I had with another “vertical” mice I tried – it supports my whole hand and keeps it off the work surface.
I’m a happy camper now…

You will eventually love this mouse. My wrist/hand pain was so bad I couldn’t squeeze a good handshake after years of using a conventional mouse. The problem surface without any incremental warning. Turning the hand 90 degrees offers an orientation that doesn’t allow the muscle to shrink to the adjustment of a bent wrist from conventional pointer on a flat table top. It really helped. Less than one week to correct and I like the button selections although it took a few days to get comfortable. It is not a natural transition and you might mistake detents above and below the scroll wheel until you use it a few times. I have the wired and wireless versions, one at work, one at home. Like them both and recommend either one. Every now and then it does hang up and not provide cursor movement at all. A quick flip of the on/off reset on the bottom resets it perfectly and instantly. You have be careful that you don’t inadvertently hit the bottom button with your pinky. This coverts between left and right handed employment. That will mess with your mind until you remember it exists after someone accidentally hits the button.
