Logitech TrackMan Wheel

Good – This is an addition to my original review. Since I have been using this mouse for the last eight months I have found that dust build up will prevent the ball from moving. I find that about every month I have to get a brush and squeeze the bristles inside the mouse and do a really vigorous clean to get the ball moving again smoothly. When the dust comes out of the mouse I find large balls of it. It is amazing just how much dust gets inside. I have reduced my rating from five to four stars because of this. A very good mouse overall. Dust build up will cause the ball not to track as smoothly.
