Not the best of Logitech's, but second best. This is my 5th. The best however was the old "Trackman Marble FX" which they don't make anymore unfortunately. Using a trackball is an instant cure for carpel tunnel syndrome you get from using a mouse.

This is my 3rd Logitech Trackman Marble Mouse. Must be something that I like about it. A couple of years using it to play Skyrim and then it is time to get another one. Skyrim must be pretty rough on it.

My whole family now uses this trackmaster style mouse. Easy to use and years and years of use. Never miss a beat.
