Good material but bites back
Size: 20 sqft
Very good product for my rear trunk and backseat on my mustang. I would recommend some type of gloves due to the foil itself when placing down will cut up your hands and fingers. Overall good product for its price.

Great product for the price
Model: 197mil 31 sqft Car Sound Deadening Mat, Model: 197mil 31 sqft Car Sound Deadening Mat
This sound deading material has a good thickness to it. It seems like the cab of the truck is cooler inside from the heat of the motor. It’s easy to install and easy to cut with a razor blade. The quality it’s an 8/10 the only complaint I have is the adhesion will stick to your fingers if you are touching it when you peel the backing paper off. It stick to the truck great tho. It covered the entire floor and back wall of a single cab truck.

Used it on HVAC ductwork did its job and stuck well
Model: 197mil 31 sqft Car Sound Deadening Mat
There was a lot of material in here for the money, so a decent value, I used it for some extra sound deadening on the ductwork in my house before finishing the basement, seems to help cut down the echoes coming through the ductwork. Overall the product was good had a few pieces where the sticky tore off the foam and stuck to the paper backing but all in all no complaints.
