Posturite Wireless Penguin Mouse Ambidextrous - Laser - Wireless - Radio Frequency - 2.40 GHz - Silver, Black - USB 2.0 - 1200 dpi - Scroll Wheel - Symmetrical

I have 2 bulging discs in my neck and working at a computer with repetitive motions really causes me pain. I have tried every ergonomic tool out there ( chairs, standing desks, PT, stretching, fancy keyboards and mouses). This product is an incredible tool in my toolkit for managing pain. Being able to switch between hands has made my body pain almost go away completely. Can’t recommend it enough! I also love the shape because it replicates the natural way our hands are supposed to sit unlike of a mouse where your palm faces down, which twists the arm and shoulder muscles. My only wish is that it could come with a padded carrying case. Other reviews say that is breaks easily and I would like to prevent that possibility with a carrying case.

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

Very straightforward to use. Just plug and play. Rechargeable. Very comfortable to hold. Can be used with left or right hand in one device. One issue is the right click button where I would use my middle finger is too high. It’s higher than my natural placement of the finger, so each time I feel like I have a second delay as I have to consciously move my finger up to right click. It can be annoying as you mind would be thinking about the particular thing that you need but then you have that 1 second interruption because of the right click you need with the mouse. These mouse clicks should have been more of muscle memory if they had designed the right-click button a bit lower. Big deal? Yes, for me. I have switched to use Evolent instead.

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

I have tendon issues (not carpal tunnel) in my wrists. I need as vertical a mouse as possible and this beats most other ones I tried. I also like that it has the bottom wrist rest. I used other types and my wrist bone starts getting rubbed raw when I have a lot of Excel and PPT work to do. This one protects my wrist from that. I got the Small (my hand is about the same as the measurement in the product pic). Fits perfect vertically, but feels slightly wide in the grip. Still more comfortable than other small ergonomic ones I have tried and still gave it 5 stars. Liked it so much I got one for home and one for work. I put penguin stickers on it.
