Your MouseRug was recommended by my friend Anthony C. who won the customer comment of the month for April. Obviously, *I* was not one of the people he bought one for as a gift. I suppose he didn't want to guess which design I would choose. Even though I have an optical mouse, it still gets gummy on the hard-surface mouse pad I have. Anthony assures me I won't have any more problems after I receive yours. And I'll have a lovely carpet on my desk! It's a great idea. Best wishes for continued success.
