Evoluent Vertical Ergonomic Wireless Mouse

This is a best-in-class ergonomic mouse. It genuinely did eliminate my wrist pains and elbow pains from years at a desk job. Ergonomically, this mouse ticks all the boxes...
PROS
1 - It perfectly positions your wrist vertically unlike some ergo mice which position your wrist at 50-60 degrees.
2 - Its well researched design is shaped in such a way that all fingers, palm and thumb perfectly cup the mouse naturally.
3 - It has a small wing at the base for your pinky finger to rest on. So no finger rubs on the mousepad.
4 - It has 3 primary buttons plus scroller and plenty of additional functionality if required.
5 - This model is wireless!...view more This is a best-in-class ergonomic mouse. It genuinely did eliminate my wrist pains and elbow pains from years at a desk job. Ergonomically, this mouse ticks all the boxes...

CONS
1 - The chrome plastic finish is a completely unexpected drawback for me. I never knew this would be a problem until I used it in warmer weather. Because the mouse cups your hand SO perfectly and the surface is smoother than Elon Musk's latest rocket knob, there is absolutely no airflow under your hand. As a result, the mouse surface/and your hand warm up quickly. Prolonged use in warmer weather (4-5 hours) results in sweat constantly building up everywhere on the mouse, repeatedly needing wiped off. Even moderate temperatures make the mouse sticky and wet. I also own the Logitech MX Vertical Ergonomic mouse and whilst its not as perfectly ergonomic as this mouse, it's a VERY CLOSE second in terms of ergo comfort, but considerably better in terms of surface material used and thermal control.
2 - I got the large version of this mouse because going by the measurement system on their website a large would be best for my hand size. That said, I'm a finger mouse user -- meaning I prefer high mouse sensitivity so I can achieve most of my mouse movements on screen with minute finger movements appose to large wrist movements. But because this mouse is so big and cups my hand perfectly I have absolutely NO minute finger control, only wrist control. For me this results in less accurate and slower mouse movements, which noticeably slows down my work efficiency. I'd recommend the Logitech MX vertical Ergo mouse or a smaller version of this mouse if this is likely to be an issue for you.
3 - It's the most expensive mouse on PBTech!!! So Choose wisely.

I bought this mouse on blind faith hoping it would be good, AND IT IS. But I never would have ever guessed these drawbacks mentioned above without trying it first, so I hope this info helps someone make an informed decision before sinking money on this mouse.

I have used computers for 35 years and also have a very large hand (Can pickup a basket ball with one hand) Due to years of mouse and digetising I have occupational over use syndrome in right wrist and can not use a standard mouse for more than an hour. Previously used Contour extra large mouse imported from US. However recently struggled to get replacement from US. So purchased the large evoluent mouse as replacement. Took a little getting use to, but now love it and do not get sore wrist and would recommend it to anyone who suffers from OOUS.
