A while back, my husband was complaining of wrist pain. So, being the loving wife that I am, I started doing some research. Long story short, I ended up going down the rabbit hole that is ergonomic mice. I read a lot of good things about vertical ones, then I also saw a bunch of articles about trackball mice being amazing for your wrist. I couldn’t decide, so I was gonna order one of each to give them both a try, but then I ran into this one from Kensington (Pro Fit Ergo Vertical Wireless Trackball) which has a vertical design AND features a trackball.
