Very pleased
Color: Black, Size: 8' Wide x 30" Tall
This works great, and I find it to be very effective at soundproofing. The hinge is good quality, and it rolls up easily. It is slightly on the heavier side, but that is to be expected considering its larger size. The materials used to make it are top quality, and it will last a long time.

Trying to limit the sound from the basement.
I still am in process of evaluating the function of these but from an early assessment they do seem to help take the noise down a peg. I have installed these between the joists in my basement so that as my kids get ramped up playing video games it could possibly help prevent the sound from rattling the house. I did not need to use the sticky side for this as I was able to slide them in place around other things to hold them still. With four panels I have ok coverage of the area and if they continue to prove effective I will get more to fill out the area even more. They appear well made and of good size but I am not an expert in sound absorbing materials. Still so far so good.

Not like egg-crate foam, but these look nice and help with noise
Everyone is putting these on the walls. I opted for the ceiling.
Back in the middle of the pandemic, I converted a corner of a back-room/work-room into a home office space for my work-from home activities. It's a basement, and so it's concrete walls, but I did my best to put things on or in front of the concrete to dampen sound. But I didn't spend any time thinking about the open-rafter ceiling, which is really just the main-level floor. That's where these (and a couple other) sound-reducing tiles came in.
I tacked some packs of these overhead, and immediately noticed a fair reduction in noise in my "office," as well as noise from upstairs. But they also had the effect of reducing my ceiling height, making it easier to warm the space when it's cold. And they look good doing it, providing a pretty nice ceiling.
These tiles are not very thick, not like true acoustic wall materials. So you're not going to get the sound dampening of egg-crate foam. But they do offer some degree of reduction in ambient noises. And they don't cost a lot. Overall, I'm pleased and think I need to order more for some other areas of the room.
