Review: If you did the prep work this stuff should last a good long time. - Clean the walls well and be careful...the adhesive is VERY good. Easy to use and the room is almost completely soundproofed. It's great. Be careful.
Review: Cornhole board soundproofing! - This is a quality product and does the job that I intended it for most people use it for soundproofing in a car, but I put it underneath my cornhole boards to take away the thud and dead in the sound so I can play a little later at night. it does just that, just remember to use a roller to secure it tightly in the corners and center.

### ⭐⭐⭐⭐ Helps a bit

Used on the bottom exterior & interior of an indoor fountain (sits on tile) to help mask the hum of the pump. Not gone but definitely reduced, and the pump noise is now less than the water noise.
