Great underlayment and a great deal. I wish I had found this four rooms ago. I would use it again for sure!

Laid this down under an engineered hardwood floor in what is a converted attic. Very quiet, almost soundproof attic bedroom now. Very easy installation. The only thing I didn’t like is that the tape that connects each piece is continuous and when trying to get the tape to lay smooth is almost impossible. It would be better if the tape was cut into small sections, say a foot or so. I actually did this myself after the first piece, but it would be nice if it came from the factory that way. But this in no way affected the use or function of the underlayment. I would recommend this to anyone
