unless you game fairly seriously or use comp quite heavily, might not notice it but i found ratpad well worth it. expensive for a wedge of plastic but its lasted me a year or something already anyway, and still fine. the tracking is better than the desk, but depends on your desk

highly varnished desk might get tracking problems but basically if youre fine with what youve got, dont bother

i play FPS games a lot though, and found the Ratpad well worth it, much smoother. Everglide also are meant to be good and the ultimate pr0-gamer fashion accessory

is probably currently a "fUnc sUrface 1030".
