I developed wrist pain when I was working as a corporate lawyer. Instead of a mouse, I then tried trackballs large and small, and then someone suggested an Evoluent vertical mouse. Within a few days, my wrist pain was gone. I used it for years, until I left the firm.

I am no longer a lawyer and now use an Apple trackpad. If I started developing problems again, I would get an Evoluent mouse for sure.

I've never used that particular mouse, but $110 seems steep to me. $40 used seems pretty reasonable though. Fwiw I got a $25 ergonomic mouse off Amazon that has served me well for two years now.

I agree with the article though, it works great and no wrist pain at all. I even game with it.
