Kensington Expert Mouse Wireless Trackball (72359)

I bought this mouse because the mouse provided by work was sorely inadequate for the amount of mousework that I do. The track ball glides (sometimes I get a little over enthusiastic about spinning it), I love the ring around the mouse that is used to scroll up and down; it feels easier on my wrist. Speaking of wrists, the only thing I don't like is the wrist rest that came with it; I like the idea of the wrist rest, but this is solid, there's no cushion-y feel. It's better than not having one, but I wish it was a little softer. Overall, this has been a great purchase.

This is my third purchase of this mouse. I finally upgraded to the wireless. I had an injury to my right arm years ago and had to learn to mouse left handed. I was so successful in training my left hand with this mouse, that it’s remained my preference. I switch back and forth to my right to give my left a rest on heavy workload days. Which is the beauty of this mouse and wireless makes it much easier. Each mouse has lasted for several years of daily use. Please don’t ever stop making it without letting me know so I can stock up!!

I love the trackball. I purchased it to eliminate the pain in my thumb from using the mouse. It has worked perfectly for that issue. I read the reviews and many commented that this was HUGE, so I expected something 8x10. But this is much smaller than I expected and I am pleased. The footprint is only about 5x6 and used less space than I used with the mouse, so that is an improvement. The ball itself has a tiny imperfection in it that catches occasionally on one of the three supports, but I had already discarded all the packaging so I am living with it. It is a little annoying, but not too distracting. I would recommend purchasing it to anyone wanting a trackball. This is so much better than the new ones that use the thumb to rotate the track ball.
