Does the job well
Style: 37.1 sqft(34 pcs), Material Type: Aluminum 197 mil
Really nice quality. There are strings woven into the top along the foil. Easy to work with. The backing peels off smooth and usually in one piece. Great value

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
