Don't buy this product--TRUST ME!8/13/2007
This mouse is incredibly laggy compared to other wireless mice I've used in the past. I basically wasted $30 because I stopped using this product 3 days after I bought it. The responsiveness of the mouse is terrible. Save yourself the money, get a Logitech or Microsoft mouse.
