5 STARS:===> BUTT, Remember to P0P the Ball out & CLEAN it's Holder once in awhile... When it needs to be cleaned... It just slows down a little Bit. PLUS, Great Battery Life. I started using Logitech BALLS even Before they Became Wire-Less. My M570 is a Great TOOL with all of my computers! I THINK THAT THE ONLY THING I'D LIKE TO SEE ADDED Would Be a M L 570 "Left-Handed" model-version TOO!
This ergonomic trackball is perfect when you don't have an area for a traditional mouse. It works in a confined area and can sit on your lap or couch and works with great precision!
