## Customer Reviews

### ⭐⭐⭐⭐ Did the job
*by M***E on November 30, 2021*

Worked well, easy to work with, took away most of the "wobble" in the extremely rough floor.

### ⭐⭐ Not as described
*by K***. on March 29, 2022*

There was no adhesive strip on product. Also it was just foam, no barrier that I could tell. Should of returned but we needed to finish project.

### ⭐⭐ It's an overpriced underlayment and the details for product were not true.  3mil stated, and 1mil product.
*by G***B on March 9, 2015*

Material is cut well and packaged without any issues for opening and installation. For the price, I would have never bought this other than to see how it was. The self adhesive wasn't the greatest either. Did it work, well slightly. I ended up using duct tape and contact cement to fix the deficiency.
