Dynamat makes two versions of this roller, a cheap one and a more expensive one.The more expensive one is rather overpriced and should probably cost about the same as this one.This one, unfortunately, is so cheaply made that it is just not very usable. The wood roller (instead of the hard rubber of the better one), means that it slips along the Dynamat instead of stretching it, and pressing it harder into the surface, which is necessary to get rid of the little gaps and bubbles that reduce performance.Even though the more expensive one is overpriced, I still recommend buying it instead of this one. If you buy this one, you'll probably be back in short order to buy the better one, and that will waste even more money.Here's a link to the better one:Dynamat 10007 Professional Heavy Duty Roller
