Garbage quality
Style: 30 pcs
Absolutely no rigidity/stiffness. Basically just a piece of foam. Not even close to a good quality sound deadening product. Whole box of 30 pieces weighs less then 1 piece of what i usually use. If you want quality sound deadening, do not waste your time and money on this product

Great adhesive and easy to separate
Style: 30 pcs
​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
