Rated 4.5 out of 5 by 55 reviewers.
Rated 5 out of 5 by Easy to work with It was our first time installing hard wood flooring. Went down really easy . Cutting was easy. It sticks to help line up the next row. Instructions clear. Cheaper than cork, which was recommended for our project, but more expensive than other similar underlayments. Price was comparable to quality of product. January 31, 2014
Rated 5 out of 5 by Great product makes laying laminate wood floors a breeze. I am really pleased with 3-In-1 Airguard Underlayment I purchased from Home Depot. The tape strip really keeps the pieces in place and I feel secure knowing that the water moisture protection is built right in. Love it. April 1, 2014
Rated 4 out of 5 by Better than the other products We have a room in our house that used the other paper products with the bubbles and we do not like it. Snaps, crackle and pops every time you walk. This product is nice, soft and sturdy. The only negative I can stay is I wish the sticky stuff was made better and able to stick to everything.. October 21, 2014
Rated 4 out of 5 by Good product Product was easy to work with. The adhesive backing strip had poor adhesion but was adequate. I am a bit of a perfectionist so I used sheathing tape to ensure a good seal where there were multiple intersections. Make sure to use good, sharp, scissors or knife to cut in order to avoid tearing and getting the little white foam balls all over the place. With a sharp blade, this was not an issue.

Rated 5 out of 5 by the good stuff it has a good thickness to it, the plastic layover piece and adhesive is pretty cool. a piece of duct tape to hold your sheets in place works well also. i wish it was a bit cheaper but you pay to play. i'm looking at order the cheaper $10 stuff online because the 2 in 1 isnt exactly "needed", but the thickness is an added bonus. the end pieces are not always exactly straight, over the last week i payed 13 rolls of this. a good sharp blade and it's easy to cut and if you take a laminate piece and line it up with the printing and make your cut. i would say this underlayment IS a good investment, remember, a good laminate floor will last you 10+ years anyways especially devoid of moisture influenced environments such as a kitchen or bathroom.
