The first thing I noticed was the quality of the adhesive. It’s incredibly tacky, which is exactly what you want—once it’s pressed down, it isn't going anywhere.It was easy to trim with a standard pair of scissors. Definitely makes a huge difference in rattles and quality of music inside the cabin. highly recommend and great quality for the money. The back comes off with ease and super easy to cut and place.

It’s not bad read my review

Style: 30 pcs

It wasn’t too bad as a finisher on top of actual sound deadening. However, be sure you apply it where you want it as it does not come off. If you try to pull it off, it leaves a nasty residue and some of the foam sticks to said residue

I used this sound deadening material in my car during an audio and interior upgrade, and the difference was noticeable immediately. Road noise, vibrations, and rattling were reduced a lot, especially on the doors and floor panels. The car feels much quieter and more solid while driving now. The material was easy to cut and apply, and the adhesive stuck very well without peeling up. It has a quality feel to it and conforms nicely around curves and tight areas. I also noticed my speakers sound cleaner and have better bass response after installing it. For the price, this sound deadening material is a great value and definitely worth it if you want a quieter ride and better overall sound quality in your vehicle.
