Query: Horrible

The advertisement says it uses the most advance radio technology, well they have some major bugs to work out before the "most advanced' technology works. This mouse frozen my PC every time I booted it AND the RF would not even go through 1/2 inch wood desk with glass top. What a joke, because the manual suggests that you mount the receiver UNDER your desk. LOL. Just reinstall my Logitech cordless ball mouse and back up and running. Save yourself the time and money and look at some other optical.
