Query: Mac users beware!

This mouse is advertised as Mac compatible, and in a sense it is. It works as a standard mouse. However, the software driver CD that comes with the mouse is PC-only, and the drivers available for download from their website is PC-only.The wheel doesn't work on a Mac, and you can't program the buttons (they all work like a standard mouse button).If you're looking for a large, clunky mouse, however, then this is the product for you.
