Title: Love it, had to buy a 2nd one for work
Review: My doctor actually recommended that I use a trackball due to a shoulder injury and I was already using one at home, so I bought a second one to use at work. I like this one especially because I can click with my thumb and navigate the ball with my middle finger or index and middle finger together. I don't like the ones where your thumb controls the ball, I don't have as much control over my thumb.
