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

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.
