Title: Track ball heaven
Review: This is my third track ball mouse, the first, also a logitech with a "center" ball, I hated. This one is the second side ball logitech I have had, and I found it hard to use a regular mouse when I had to replace the first "side" track ball mouse. The wait of 4 days was LONG.Once you get used to a side trackball, it is so easy that you will not want a regular mouse.
Is the review positive or negative?
