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

The Posturite mouse is excellent for me. I tried with two different sloping mice; these helped with the angle of my wrist, but acted as a wedge to force my thumb into an uncomfortable position which produced strain in my hand which I didn't have before. This is the only mouse I have found which has eased strains in my hand and wrist. Two smaller issues: 1) I went for a mouse slightly smaller than recommended, and it's fine for me. 2) I am using a slower "Push DPI" speed than I had done before (a button the bottom of the mouse controls this), to enable me to have better control over the mouse pointer for clicking on small buttons and crosses on the screen. At a slower speed, I am able to control the mouse well. I did notice issues with controlling the mouse at faster speeds initially, and I also found that if I put my little finger on the desk beside the mouse base, that gave me more control (and it would be easier if the base were a little smaller); at the slower speed, I don't need to do that. It's more expensive than other mice, but the relief it brings is well worth the price.

Because I use my mouse a lot I suffered from repetitive strain injury in my right hand and arm for months. Been to doctors. It really messes up with your everyday life because I use my right hand to do everything and the pain would be constant. A hand massage would only relieve it but not heal it. This mouse has completely got rid of the pain for me. I can use it for hours non stop and my hand doesn’t ache as much. I am so grateful to whoever designed and built this. It is well worth the price. Highly recommend especially for techies.

This mouse has a lot going for it, but Posturite should really redesign it after so many years to address some of the obvious issues with it. Firstly, the sizing I feel prioritizes those with larger hands, and there should be an extra-small size available. According to the company's own sizing recommendations, I should use size Medium, but I found that was too large; size Small was much better for me, if not ideal. The main reason why is that the body of the mouse is too thick and it forces the thumb to rest at an angle that's not ergonomic. This can cause pain and tenderness over time, in both hands if you take advantage of the ambidextrous form factor. A smaller size could address that design flaw, or better yet, a redesign of the body shape. The other negative point is the mouse wheel, which feels like a liability and can get jumpy if you overuse it. There have been numerous reports of this being the first component that goes bad in that mouse, so this should really be addressed by the manufacturer. On the other hand, you get two ergonomic mice for the price of one, which is fantastic to have if you can operate a mouse with both hands. This is the best feature of the Penguin mouse, along with the fact that it forces you to use your arm muscles for movement. For that, lower DPI settings are better for precision work. Overall, I am disappointed however that the mouse doesn't quite get the thumb position right. Something like a Unimouse could be a better alternative, but then you'd need to get a separate left and a right-handed option if you want ambidextrous. It's still a decent solution, but like anything to do with office equipment, moderation is best.

Really helps tennis elbow pain. Have got used to it. Has reduced the pain significantly. Wouldn’t go back to using the old mouse Sadly it stopped working in July so only lasted 4 months. I’m really disappointed and will ask to return the product

I've used various ergonomic mice, mats, and keyboards for 20+ years, so when I was starting up a new business, with all the computer woman-hours that entails, I put in some serious research to find the best mouse for me, whatever the budget. I ended up plumping for this - mostly because I have small hands, but also partly, I cannot lie, because my inner 6th-form boy got a snigger out of its appearance (the latter wouldn't, of course, have convinced me to buy it had it not been right in all other aspects other than cost, but eh. What can I say? I don't get out as much as I used to, and a bonus snigger is never a bad thing, right?). It did exactly what I needed for a good while - comfortable for my paw, and sufficiently responsive for what I was doing (LOTS of prose typing, much spreadsheet action, website design/content creation, and entry-level video editing). As is so often the way with little tech, though, the charge port went shonky before the mouse itself had. As we all usually do with this particular irritation, I managed to manoeuvre/contort the wire (holding it at EXACTLY the right angle for the duration) to overcome this while charging for several months, until the port eventually gave up the ghost completely. I'd been sufficiently happy with the mouse until then to simply order a replacement, but that's now gone exactly the same way. I know it's not a lot of money in the grand scheme of things, and all tech has a built-in dead-by date, but if I'm paying quite a bit more than the other small-paw option I was considering (Logitech's Lift), I don't expect to have to replace it quite so frequently (first Penguin bought Sep '20; second and-now-also-defunct one bought Feb '23). It's a shame, because I was very happy with my Penguins. Until I wasn't. Based on my experience, I'd say if you've got enough cash sloshing around that having to replace your comfy mouse every couple of years (and for £60 more than the obvious alternative option) isn't a problem, then go for it if your needs are similar to mine. But for me, it's time to say hello to Logitech, and see how I get on. Hopefully I'll get more bang for my buck. My just-ordered Lift won't elicit the sniggers which this design has when visitors clock my mouse, but I'll happily live with that if it means not having to splash out for replacements so frequently.

Bought for my sister for her birthday, she loves it

Excellent item for dexterity problems. This is my second one and will buy again +++

Habe die Maus seit ca 3 Monaten im Einsatz nach einem Tennisarm rechts. Zum einen entlastet diese Maus spürbar den Arm und Handgelenk, zum anderen finde ich es sehr angenehm, im quasi fliegenden Wechsel von linker nach rechter Hand ohne Umschalten arbeiten zu können. Der Sensor ist allerdings manchmal etwas widerspenstig, ich habe mir ein Gaming-Maus-Pad angeschafft womit die Maus meistens gut klarkommt. Negativ außerdem, man muss die Maus aufladen vie USB was einige Stunden dauert und sie ist währenddessen nicht einsatzfähig. Positiv außerdem: Nachdem die 1. Maus unter Win 7 nicht störungsfrei (und unter Linux gar nicht) funktionierte, habe ich sie eingeschickt und bekam sie dann ausgetauscht, seither funktionieren Win 7 und Linux Mint (die 1. Maus funktionierte nur unter Win 8.1 und Mac (gemäß eines Tests) störungsfrei). Der Kundendienst der Firma bekommt von mir außerdem Note ausgezeichnet. Ich vergebe trotz der kleinen Macken 5 Sterne, weil die Vorteile für meine Bedürfnisse klar überwiegen und praktisch konkurrenzlos sind.

I though this mouse was a little expensive before buying it... I was very wrong, because it's exactly what I was looking for... my Carp Tunnel problem is better now (after 2 weeks using it). Thanks

It has been 5 years and it is working as good as new..

Ordered a small. Seems ok. Wish they would have told us how to measure for size. We should have med.

I have had this mouse before with no issues. Unfortunately, this mouse top mechanism for double clicking sticks regularly.
