Input:
This is my second trackman. The first one lasted through thousands of hours of use over years of use with no problems and it outlived a few computers. it finally got slowed down but still worked. It was time for a new mouse and I went back to the same model and it works as good as the first one when it was new. I gave it a 4 star on quality only because the adapter on the end of the plug didn't work. I had to use the old one. it is an ituitive design that just works.
