Would've been nice to know the wall tiles don't come with adhesive but the shipping was extremely fast and they work great. Not the perfect solution to noise but helps to muffle loud sounds you dont want everyone to hear.

These work really well. I didn't wait 2 days. I had them ready to post up within 6 hours. After pulling it out of the plastic they began to rise by themselves. I quicken the process by simply gently pulling the stubborn corners in each direction. I also got them to fluff evenly all around by gently tugging opposite corners as well as the mid left side to right side. Pulling too hard would probably rip it.To rid of the smell quickly I stood each square upright in my bathroom-- some against the wall, and some leaning on each other-- so it can air out. The major thing that helped here is that I have an exhaust fan in the bathroom, and so by closing the door it sucked air through the foam even more quickly. Didn't have to stink up the house or leave it outside where allergens might grab on.As for adhesion, the thing that worked for me was letting spray adhesive on the backside, and then using velcro with the adhesive backs on them.This doesn't cancel out noise completely like some people expect here... but it definitely does a great job dampening to a large extent. I have thin windows, and the neighbor hasn't had a problem with me since.

I purchased these to put on a window facing a very noisy street. They help reduce the noise a bit but I also have sealed the window and put up a noise reducing curtain so I am unsure how much noise they are actually blocking. They don't have glue or glue backing, so I had to this myself, which is fine but my main issue is the fumes emitted from the chemicals on them. The first night I slept with them on the window I had a horrible migraine from the fumes. I thought about returning them but I really need them because the street noise is unbearable on my bedroom. I've been aerating the room and running two air purifiers but night 3, I have a migraine again from the fumes. If it keeps happening I may need to reconsider.

Have not noticed a difference in sound. Keep falling off the walls.

Sound dampening adequate for price point. EZ PZ to cut to shape for interior closets.APPLICATION : Wasted ! = moneys for double-sided tape, augmented by gorilla adhesive.BEST APPLICATION : Arrow T50 staples 3/8 in. 2 - 3 zaps to a square.Hence. : 1. Strategically placed, no show. 2. No worries of Tape or Glue destroying paint.To remove squares, tear off & gingerly remove 2 or 3 staples.

Used to insulate inside the HVAC ducts.The adhesion is surprisingly strong.The product does have an odor but that quickly evaporated.The sound insulation is adequate.After my initial review which had some concerns the seller reached out to me an offered a full refund. This is something you do not see every day and should be appreciated. Such gesture should encourage any potential customers to do business with this seller.

The foam pans looked great. I had an issue with a few of the panels I left a review and the seller reached out quickly and offered a full refund.

These have not been installed yet so how they perform is yet to be seen (or heard). These were packaged so tightly that about 8 of the 24 did not fully expand on one edge. They have been out of the package for over a week. My plan is to use the ones that are not fully expanded at the bottom of the wall. I also hope that double stick tape will do the trick. The quality seems good.
