They unfolded and straightened out very fast!

Don't bother. It's basically garbage

Why did you pick this product vs others?:Product is smaller than listing, 46 inches x 22 inches at best, even after following all instructions. not a big deal, unless you are trying to match already installed panels, and expected to receive the same size.

This product suited my means for dumbing down excessive Noise over a Door cutting to Fit keep in mind it expands up to when unpacking.

Bought eight of these and they all came the same size and they were pretty thick. Haven't put it up yet, but satisfied so far with what I received.

I was skeptical how well they would form back after vacuum sealed. Just plan on giving them some needed time after unpacking to form back to original shape.

Used as bass drum muffling and am very impressed by it.

yeah i would go with the smaller squares that actually have adhesive.
