USB Wireless Finger Handheld Desktop TrackBall Optical Mouse Mice With A Receiver

Love this thing. It's a bit to get used to cuz of the size, but get used to it you will. Had a trackball years ago and loved it. Hand held one is perfect. And it works.

I needed a hand held track ball and this one fit the bill. The only thing it lacks the ability to change the functions of the buttons. But otherwise it's a nice little track ball.
