## Customer Reviews

### ⭐⭐⭐⭐⭐ Well made.
*by S***E on May 1, 2025*

Nice acoustic panels, works for my room with the others I have.

### ⭐⭐⭐⭐ Not bad, decent panels…
*by S***1 on January 13, 2025*

Overall they are pretty good except be aware… They aren’t 20”x20”. They are slightly less and length and width are not the same if you want to switch pattern direction. Also slightly less than 6” tall. It would also be nice to have had a thin backing covering the entire back in order to mount better, plus make it more ridged. Lastly, some of the tabs that are painted black didn’t get painted completely and I had to touch them up. I’m happy enough and would buy again.

### ⭐⭐⭐⭐⭐ Super Quality
*by V***C on September 17, 2024*

Great product! Uses real ACCOUSTIC foam rather than mass market pseudofoam. Looks very classy and works. When I move, I'll throw the thin compressable egg crate stuff away, but carefully pack this away to use ar the next location.
