a plain black cloth covered foamrubber mousepad you can get anywhere for $5. i prefer the 1/4" thick ones you can get for a little more at staples.
do you really want to spend $58 on a piece of plastic that does not improve your game at all? for a quarter of the price you could get a basic mousepad of the same size that will work just as good.
believe what you want... just realize that most of the products directed at gamers are often not the only, and sometimes not the best choices.
