          Inconsistent quality of the rolls
          No issues with underlayment characteristics, it works good for our floating bamboo flooring. The issue is the inconsistent quality of the rolls. We’ve got 6 rolls for the project and 3 of them had bald spots throughout the whole length of the roll.

            Under layment made a difference on my floor by reducing noise and adding a bit more comfortable feel under my feet.

            Destroyed our vinyl floor
            Home depot recommended this to us when purchasing Nighthawk flooring. Everyone said it was easy to work with, and they were right. They said I would love it, but after being told this is the reason my $4000 in flooring is falling apart under my feet, Im not loving it any longer. Now we have a busted floor, and no one will accept responsibility.

              Great Quality
              [This review was collected as part of a promotion.] This flooring underlayment is such great quality. Not only is it easy to use and install but it has so many additional great features. With the vapor barrior it is great for sound suppression making it very quiet which I like. I also love the moisture protection since I am using it on a cememnt floor. I always worry about moisture when put flooring down. The best feature though is the compression resistance, so amazing. No more dips or impressions making it look horrible. All in all this is a very good quality product that I would highly recommend.

                Almost easy
                So I went with because of the thickness and review rating. Pretty easy to work but the adhesive is too far away from the edge for the plastic lip to adhere to it. Maybe I got a misaligned roll but the seams were flush and I had to stretch the plastic to get it to the adhesive strip, which caused the edges to overlap, so I had to forgo the "handy lip design."
                  "Quietwalk" is a misnomer
                  Replaced cheap plastic underlayment that was recommended by my installer, and installed Quietwalk in it's place. Unfortunately, Quietwalk is anything but quiet. The floor now has a distinct hollow sound, and if you're wearing shoes it sounds as if a parade of horses is walking through your home. Additionally, the floor now has a spongy feeling when walked upon vs the solid feeling in the rest of the home. The flooring visibly moves up and down vs no movement before. May end up replacing again.

                    Perfect underlayment for floors.

                    QuietWalk is pretty loud
                    We installed luxury vinyl flooring in our home in 2 stages; two years ago we did half the house using a vapor barrier and generic plastic underlayment (not QuietWalk) and this year did the rest of the home using QuietWalk. The flooring 2 years ago did not have a foam backing, but what we got this year did. Same SKU, but the material changed. The flooring from 2 years ago feels tight to the concrete floor, has almost no "give", and is pretty quiet. The flooring from this year feels bouncy when you walk on it, and is really loud. Like, the cat jumping off the bed and walking down the hall in the night will wake you up. Even with just stocking feet, there's no way to walk quietly on the QuietWalk half of the house. It's not just a little louder, it is significantly louder. The wife prefers the feel of the half without QuietWalk, but I prefer the feel of the floor with QuietWalk. We both agree on the loudness comparison though.
