uxcell Car Studio Sound Acoustic Absorption Heatproof Wave Foam Deadener Mat 78.7"x39.4" 21.5sqft

Noticeable improvement over using just Dynamat alone

Excellent sound deadening. Used on the inside of the door card of my GR86 when upgrading the speakers. The material feels very high quality and the adhesion made it very easy to install. The large roll makes it easy to cut the size you need for clean application. High recommendation.

Don’t waste your time or money. Amazon made me edit my review due to there “guidelines” so can’t say what I really want about it.

This isn't stuff you would use in a studio, but I used it to put a border around my door frame to keep out some of the noise from the living room. It works great for that; the back has a sticky adhesive that is easy to take off the wall if needed.So far it is serving the purpose, give it some consideration.

Works good. Only wish it came in a roll instead of being folded. It has fold creases.

Great sound proof for car, eliminates sounds from the outside

Absolute garbage for 40 bucks couple of feet of material. It comes folded wrinkled with stretches and cuts. Not something you can use in studio or car interior. Not worth it's money and definitely not as neat and good looking as on their ad pictures. Home depot has the same foam for like 20 cents fer feet. Get some $4 glue and save your money. Do not fall for pictures this product is garbage

The foam was flat, think & there wasn't much of an egg carton foam type shape or thickness?
