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!
I love it! Works like a charm. I have arthritis in my hands and this trackball is perfect for me. Easy to use and doesn't cause as much stiffness in my hand as a regular mouse.
The trackball has always been my favorite pointing device and I have never had a wireless one until now. The Logitech m570 is the coolest one yet. With forward and back buttons , wheel scrolling and thumb ball all at my finger tips its quite a pleasure. And dealing with Overstock was a pleasure.
