Title: Works great until it doesn't
Review: I've had this trackball for about six months. Worked great until last week, when it started not working at all. Now I have to push the "connect" button every 5 minutes to get it to work. Pretty typical for Logitech trackballs in my experience. I've had two or three of the trackballs with cords and they crapped out after a few months, too. I won't be buying another.
