Bang for Buck

Its pretty good sound deadener and it includes enough to do your doors. My door went from sounding hollow to solid. It definitely made a difference in the sound quality.

Wonderful

I used this in my doors and trunk. I tried other sound deadening products from Amazon that were trash compared to NVX. Easy to cut, easy to place, stays in place, and is thicker than the competition.

Pliable and sticky even in cooler condittions

I like it! it was in the closet and I took it to the garage it was 45º this stuff still conformed to the curves and stuck like crazy even in the cold!
Love the color I was using another brand (silver) and where the seat doesn't cover its highly visible black makes it blend in with my black truck.
looks nice and deadens like it should!

Good value.better than name brands.

I bought this after using the chrome version of this. I liked that it was black and had a “better look” than the chrome one. Even do it says it’s the same thickness as the chrome one it feels thinner but the same thickness as the stinger roadkill. I did find that it was easier to work with than the other nvx version and stinger. It is still a good value and has hold up since 2017 in the Northern California weather. If I had too choose between the nvx chrome one and this black version I would go for this one if looks was a concern other wise the chrome version is a better value.
