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!
Several years ago my DH got a thumb trackball on a wire for my desktop. I hated the thing the first week or so but have come to appriciate it since. I am older that dirt and my hand trimbles sometimes and I never could use a laptop because that arrow would not go were I needed it 98% of the time. Then I found out about cordless mice for lap tops but when I looked at the computer store and there were not thumball type. So I decided to see if O had them. When I found this I knew I could get an lap top and did. So even though I got the laptop first I picked this out to buy first.
