Mad Catz' MLG Pro Circuit controller is aimed squarely at those who play games professionally -- or would like to. We put the PS3 version of the handset through its paces and found that while it's highly customizable, a lack of Sixaxis, force feedback and pressure-sensitive buttons made the gaming experience feel lightweight. Are you a gamer and did you buy one? You've had six months hard labor on this thing, so why not tell us what you thought of it and if you were asked, what would you change?
