## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Product and Unbeatable Price
*by J***W on March 30, 2016*

Can't stress enough how happy I am with this product. Great performance and quality. Saved roughly $400 from buying at the big "Orange" home store. I would highly recommend using this!I have installed 5 floating floors and this is the first time I used this product. Any floating floor I every do will be with this going forward. The product is fantastic. Very easy to work with. The overlap adhesive worked well for me and I had minimal mess from the white balls. Used household scissors to cut this.Installed the cheapest floor I could find (in stores) on top of this. It takes all of the echo/hollow sound out of it. As well as gives nice cushion and warmth. This application went right over a poured concrete floor. The finished piece compared to the bare concrete was noticeably warmer.

### ⭐⭐⭐⭐⭐ Great Value For The Money
*by U***U on December 13, 2024*

This was a recommended product at one of my local "home" stores. It just made more sense to buy it here rather than pay for multiple rolls there.Functionality: Product is straightforward and easy to use.Durable: Kinda hard to answer this since you're only sealing the top side together, leaving bottom open to interpretation. Also when tapping boards together you will occasionally hit against this pad creating a tear. Quick fix duck tape and keep moving.Smell: Nothing overwhelming, if any at all.Adhesive: Once layers are placed together, there is an adhesive strip that bonds them together.This product was super easy to install and super easy to use.
