Rated 4 out of 5 by Easy to install - would likely purchase again. the FloorMuffler is supposed to have the highest sound absorbency rating on the market at the moment. I can't really tell a difference between my old floors (with no sound proofing) and the new floors with underlayment, but i've only had them completely installed for a few weeks - i'm hoping a few more months of use will make the purchase and installation time worth it. We bought two rolls for 148 square feet but with the odd angles we almost ran out even though it was supposed to cover 200sq feet - we ended up making some strange cuts and using up the scraps, which worked fine. I really like that since it was so flexible it was easy to cut in place with a box knife and get it right up against the wall (or under the sheetrock lip). It was very easy to install, just lay it down and peel the sticker strip. One thing that was difficult was that the interior of the roll(s) had been crumpled and was difficult to get to lay flat (even after using the sticker strips) until the floors went on top - we solved that problem with a few small boxes laid around the room. FloorMuffler was very light and easy to maneuver as well as very thin - so our new floors were able to very closely match up with the old ones. The instructions weren't very robust as this is a new product, but i wouldn't recommend walking around a lot as shoe tread leaves a semi-permanent indent. I don't imagine this would change the performance, but i suppose it could. April 22, 2013
Rated 4 out of 5 by Nice Product! This underlayment was very easy to use and install. My only concern was it seemed to rip easily. December 10, 2013
Rated 5 out of 5 by New Flooring The product is very nice and looks great-variation of colors hide dirt and shedding. July 22, 2014
Rated 3 out of 5 by Great product, but.... This is a great product but there are a few things you need to know: 1. The "adhesive" is worthless 2. The white plastic on the end without the adhesive is also worthless. 3. DO NOT USE EITHER ONE. Make sure you sweep your floor REALLY REALLY well and buy several cans of 3M General Purpose Spray Adhesive (Store SKU # 251128 or Internet # 10018461). It makes a HUGE difference and makes it possible to roll this stuff out with one person. Do not buy this underlayment unless you are going to buy some sort of spray adhesive. August 25, 2014
Rated 2 out of 5 by Easily torn. No printed grid to make cutting easier. This needs several things to make it better. It was the one recommended, and might be the best -- which would be very bad. This needs a denser layer to add strength against tearing. it needs a grid pattern to help get it straight and to guide cutting. It also should be in a wood color to make it less noticeable if an edge shows when the floor gets shifted. Add instructions to roll this out for a day to get it to "relax" for easier handling.
