Title: Worthless. Big Mistake!
Review: The scroll wheel on the mouse doesn't work. Sometimes it does nothing. You are just wasting your time. Other times, it scrolls down a little, and then jumps back up. I use the scroll wheel alot and if it doesn't work, the mouse is practically useless to me. I should have bought the keyboard as wired, which would have been less money, and then a competitor's mouse. Microsoft needs to learn to do it right before putting junk in the marketplace.
