Rated 4.0 out of 5.0 by Works fine; larger size a price performer. I've only just laid this stuff, so I can't vouch for how it lasts, but I found it to be about the cheapest option out there for plastic underlayment, and it seemed strong enough to do what it was supposed to do and lay fairly flat despite wrinkles and creases it came with. This larger size is definitely a price performer; if you've got more square footage than what two of the smaller 120-sq.-ft. rolls can cover it's worth ordering this larger size to save money. I also found the larger size to give me a little more flexibility in covering my large spaces without so many seams, though you may end up wasting some at the edges. July 28, 2015
Rated 5.0 out of 5.0 by Good Product Product came in one 700SF roll that was far cheaper to buy than the 150SF rolls for my project. Product is very thick and durable and held up to walking on, stacking flooring on and using tools to install floor on the moisture bloc. After floor installation moisture block felt solid under the floor and made no noise when walking on it with the floor on it. When cutting I used scissors however cuts better with a razor blade knife. Overall a good quality durable product. August 26, 2014
Rated 5.0 out of 5.0 by good product Not in stock in store, but only took a few days to get it shipped in. Clerk I worked with went above and beyond to help me, including getting my Veterans discount. We installed 750' of Pergo flooring our selves, this product with its color, made it easy to follow are lines. It was also big enough to cover a large area so we didn't have a lot of cutting and piecing together. Would highly recommend this product, especially for DIY person that I'm. Thank you Home Depot and your helpful workers. Nick Venero January 24, 2014
Rated 5.0 out of 5.0 by If you install flooring on concrete, then you must use this Works great. If you live in a house with concrete floors, then this is a must in order to keep your floor nice for years to come. January 23, 2013
Rated 5.0 out of 5.0 by This product was easy to install. This was easy to install. The only problem we encountered was it moved easily even after we had taped it to another piece. I would suggest for anyone who is using the product to only lay a section at a time. This was our first time installing bamboo flooring so a process of elimination on how to do things was expected.
