Like everyone else here, its overpriced when you figure it cost probably $4 to manufacture. But if you're laying down dynamat on the entire car surface, floors, doors, trunk, rear deck, firewall, door interiors, the works! Its worth having, still, you'll use a large ratchet handle or other stiff big object to squeeze the mat into corners and oddly shaped areas of the car. But its so much easier to roll it omitted versus rubbing your hand across the car surfaces. I do wish dynamat made it with a longer handle for leverage and better control, the handle on this thing is short and miniature.
