Yes, but is it wireless?

I have three of those here and other family members have the same, no 
traditional mice. They build up a little cushion of lint at the rolling 
points but it only makes the ball rotate less freely. Conventional mice 
accumulate crud on the rollers that has to be removed with a bit more 
difficulty. I have never seen a switch failure on our Logitech "track 
balls."
