24 Packs Acoustic Foam Panels Pyramid 2" X 12" X 12", Soundproofing Foam Noise Cancelling Foam with 120 PCS Double-Side adhesive

Alright so I'm aware that some of the biggest issue with this product is 1) the double sided adhesion stickers and 2) squished/flattened fpam panels.I found the best way to address peeling the covered side of the sticky pads is to actually rip it. The pads themselves have some stretch to them, so you can actually gently rip the covered covered portion to allow you get a better grip on it. Once you try it, you'll understand. (Don't try and peel it, try gently ripping the yellow paper and it'll be way easier to manage)As for the squished panels that don't seem to inflate, another reviewer mentioned that if you run it under some water (warm or otherwise) it'll inflate just like the others. I had a really flat one that might as well have been 1" or .5 inches but after running it under some water, it inflated like a sponge.You can squeeze the excess water and just set it outside in the sun to dry off. (or use paperwork towels, whatever you have).Great product and came as intended. May update my review in terms of sound absorption. ('m aware this isn't a noise cancelling product, those cost way more).

I have ordered two packs of these. They arrive vacuum packed and flat. The first pack took a couple days to expand out to the 2 inch depth. Some of the pieces didn't expand the whole way. The second package popped out to the 2 in depth within minutes! So fun to watch. :) Easy to install. I'm still hanging them in my booth, so I don't know about sound mitigation yet.

Birds outside my bedroom window had started chirping loudly at 2:00 and 4:00 a.m. I put this on the windows and I don't even know they're there now. Awesome

The double sided tape did not stick as advertised. Not pleased with the product

The panels are squashed on arrival on the one side. Every single panel was like this. There wasn't a single panel that wasn't squashed. I tried to pull it out and it sort of worked but resulted in ripped material and took me like 10 minutes for one panel. I don't want to spend 240 minutes fixing a defective product to have them wind up it still looking like crap.

These are good. We put them in an extra bedroom that we turned into a drum room for my husband. We live in a 1400 sq ft home. So, it really helped a lot when we put these up. It brought the sound down. We also wanted to be respectful of our neighbors. Which it has helped.

Quality and price were good.

They work but don't stay up. Not worth the price if the adhesive doesn't work and I have to buy extra stuff to keep them where they work. Would be cheaper to buy foam and make panels yourself.

The foam acoustic panels worked perfectly, once I put the stickers on the foam panels I had a really hard time peeling of the paper part of the sticker maybe because of my big hands but other than that they worked perfectly.
