Well, this certainly isn't the best purchase you could make. Soft mats generally tend to bunch up if you're really dancing hard on them, and this one is no exception. It doesn't pick up all of the steps you make, so you end up with a mediocre score. Of course, it can be modded to work better: just attach it to a large piece of plywood and it should work okay, but this mat is just not for those of us who intend to be *really* good at DDR. Good for beginners and occasional players, not for people who play in the arcades.
