Harmony 630-Square Foot Roll Underlayment

After doing a lot of looking around for an underlayment AND moisture barrier for my engineered wood flooring I came across this in Home Depot. After seeing that it did everything I wanted in one product (instead of having to buy 2-3 separate things) I was skeptical but my interest was piqued. I came home and while doing some research found that it was even cheaper here on Amazon so decided to take the plunge. Turns out it was absolutely worth it. This stuff is dead simple to install and does help the floor sound great (there's none of that "empty" sound when I walk on it). I also did a quick, simple little moisture test of my own (poured some water on a spare piece to see what would come through) and found it worked quite well. My only complaint is that some of the little Styrofoam balls came out from between the two "sheets" which caused a tiny bit of extra cleanup but more importantly makes me wonder how this will hold up long term. Guess only time will tell for that one.

This is agood product for much cheaper price on amazon.The hollow sound i believe not only depends on underlayment but also on the laminate.I used this underlayment for 15 inch laminate and have no major complaints.Only issue i had was cutting it.Its kinda difficult but i guess it is same for any other product.I dont have any hollow sound.overall i recommend this.

Good stuff and easy to install. Big roll a little harder to handle at first. Saved about $150 buying this big roll.
