doesn't work very well
I wanted to like this mouse, and have used a similar one from Kensington with great success for years, but for some reason it just doesn't work very well and is a great disappointment. Now I have to go out and buy another brand of the same thing just to get work done! It's way way too jumpy, on any number of surfaces I tried. It keeps releasing the item I've selected too soon so the amount of clicking and dragging I have to do just to get one thing done has been increased tenfold. It jumps the cursor all over the screen when my hand is just sitting still not moving. Very frustrating to use. Can't wait to get rid of it.
