just had surgery today, can’t use right hand really atm. got a left handed mouse to use for now. saw an ergo mouse and said wth, lets try it. omg what a difference. sooooo much more comfortable and natural feeling in the hand then traditional designs.
I had a Logitech MX Vertical for a couple of years now. A bit pricey but what a difference. I use to have pain in my arm and shoulder, but once I start using it it went away.
I totally recommend a vertical mouse, even for gaming it′s no problem. Once you get use to it it′s like a regular mouse.
