I Would Buy This Product Again
The product is of very high quality and goes down rather nicely. The plastic vapor barrier is substantial and includes an extra 3inch overlap to be taped to the next row. I did a sound test using various objects on the floor with underlayment and without on a concrete floor. Quite frankly we could notice very little difference but it has to be providing some sound deadening. Either way now that the floor is finished we are happy with the choice of underlayment. I would buy this product again.
