Does anyone have any experience with the M2 Racer pedals? Are they the next great thing or something that I would wish I hadn't bought?

I haven't used them but from the looks of them the pedal shaft would wear on the plastic part of the cleat. The sleeve on the pedal must rotate. But do you think the plastic would dent or wear after a while? What kind of stack height does it have? The closer you get your foot to the center of the pedal the better.
