Thickest butyl deadnening mat if seen so far. Good quality with good adhesion. Not sure if the extra thickness is worth the extra cost tho. But if money isn’t an issue I would recommend trying this over other brands.

This stuff is a little speedy but totally worth it in the end. I have two 12” subs in the cab of my truck and from the outside with the stereo blasting you can barely hear it. Stops almost all rattles, some plastic body panels still make noise but nothing I can do about that. Totally worth the investment.
