This BenQ Zowie 480mm x 400mm is a replacement for my Steelseries hard plastic pad (as those are only available in 320mm x 270mm) so that I can lower the mouse DPI sensitivity levels in the hope of getting better twitch in shootems. After two weeks of use I have no complaints at all and have adjusted to the longer flick distance and am loving the smooth surface which, while less frictionless than the Steelseries, feels like it stops on target without overshooting easier and better than hard plastic would. It has been comfortable to use and looks well made. Time will tell.
