24 pieces of 12in x 12in acoustic foams for under $100 is an inexpensive way to improve room acoustics. It removed all perceptible echos in my room. Made my stereo sound better by reducing bounced-sounds from the speakers. And the TV seems to have more clear dialogs. Overall, I'm very happy with the product. It came in a big box, uncompressed & not deformed. I'd rather receive it this way than in a bag that was vacuumed. Less chances of being deformed & no need to wait for it to come back to its normal shape. I didn't notice any strong smell as other reviewers have indicated. And it has a fire rating which is important especially that I placed it in my bedroom
