We love it!Review by Mark D. from Redding, CA
The Best Laminate sales crew were friendly and helpful. The Roberts underlayment was easy to install - love the tape strip on one edge that connects to the next section - requires minimal additional tape to secure the padding. Was worried about the sound deadening foam balls getting all over the place, but they stay in place very well and are not a problem. The underlayment is great at deadening the noise, even on a cement base! We love it!

Nice and quietReview by C. Moore
I has my floors installed last weekend. I was concerned about the possibility of having that hollow sound you sometimes get. I had very thick laminate, 12m so I bought what I hoped would add to this lovely laminate and this underlayment does just that. My installer says this is the type of underlayment they like to use. And those little balls are locked in place and so that is not a worry. The floor has a lovely feel when walking on it and it is not hollow. Feels like a wood floor. This was an excellent choice. Don't be afraid to buy this one.

Easy to Use!Review by Manuela N.
The vapor underlayment was easy to use. It helped the floor we installed with noise. The price was great, if we would have purchased it from a local store, it would have costed us twice as much. My mother-in-law recommended this site, glad she did. Thanks!
