Fstop Labs12 12 Pack Set Acoustic Panels, 2" X 12" X 12" Acoustic Foam Panels, Studio Wedge Tiles, Sound Panels wedges Soundproof Sound Insulation Absorbing Mushroom 9 Blocks Design (Grey)

Ordered 2 packs of 12.8 of the 24 actually expanded as adversises. A few only half inflated and most stayed completely flat.I laid them out and left them to swell for 48 hours and then some. In the first 12 hours 8 looked amazing and others looked like they were starting to do something...However nothing really progressed after that! Very disappointed!

I cannot recommend this product. Only about half of the panels regained their shape. This is after following all recommended steps per the manufacturer.When I contacted Amazon I was asked to contact the seller. The seller then offered up the same steps I'd explained I'd taken then pointed me back to Amazon.Ultimately I would have kept them if they simply replaced the defective ones but rather than do that I was offered a refund so I sent them back... Not recommended.

Bought several packs of these, and threw them into the bath tub and 12 at a time in the dryer on auto (20 minutes does not really cut it). I used a hot-glue gun to stick cardboard backing to the corners. The glue is important because the foam will flex, which easily destroys 3M tape type adhesion, whereas the glue I used penetrated the foam slightly and remains slightly rubbery when dry. I then stuck the pads to the walls using blue-tac. I'm thinking I'll switch to 3M tape on the cardboard to stop a few problem pads from coming unstuck. All of the pads expanded without distortion. The foam is doing a reasonable job of attenuating echo, but don't be fooled by any claim that it somehow decreases noise leakage or in any way affects lower frequencies. That's physically impossible. Overall a good quality product.

Me encantó, estaba buscando algo para evitar que mis bebés se golpeen al gatear y sirvió de maravilla, lo puse alrededor de su cuarto, así cuando gatean o se van de lado, ya no se golpean con la pared, están suaves y acolchado, hasta sirve para cabecera de cama, muy cómodo al recargarse, hasta decorativo se ve.

Do not buy this! I followed the instructions and had to do extra drying in the dryer and it still did not dry properly.I then put command strips on the back of these, as most people have, and the strips did not stick to the back of the foam. Probably cause either it’s STILL not dry after 1.5 hours of drying or the foam is just not meant for command strips or double sided tape..waste of my money and time for nothing!
