Works good, the feel is cheap has it is a lighter plastic not sturdy feeling like Logitech or Microsoft. The Light feature is cool and it works good with games.
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.
I have fairly large hands and do not have a carpel tunnel situation but wanted to try something new. The trackball fits my hand well and, though, it takes a while to get use to using, it's pretty fun!
