Garbage; foam and laser-cut bamboo. Basically, you are supposed to use two-sided tape to hold everything together and then stick it to your wall. The directions in the box do not match their video at all. So you're paying $100 USD for a 12"x12" piece of foam and some bamboo probably costs $20 to make. Then here's some tape. Needless to say, got the first two up and then the bamboo started falling off. Once I got frustrated enough I said to hell with it and ripped them off the wall.Now I need to fix my wall and repaint and broke 2 of the 4 I ordered. All I can say is this is the cheapest piece of utter trash I have ever ordered. I could have saved $50 bucks and paid someone to kick me in the crotch for 30mins and have a similar experience.I should have just bit the bullet and bought something that was made by a company that gives a crap vs money-grubbing garbage dealers.

Bad quality and packed in a very wrong way i requested to return them what a waste!

Definitely work. Nice straight cuts with fine edges. High density foam.I’m using mine in my 10x10 bedroom and gotta day the difference is 100% noticeable. I also paired mine with 4 foam 20cm cubes which really helps finish the look off. But paired with the cubes I must say the standing waves have been greatly reduced. Even the standing waves you’d get in the hallway (the bwaa bwaa bwaa) was extremely reduced, making for a more comfortable environment for my guests. Also bought a similar design from another company and they were NOT the same. The other company had the same design, but the foam was softer, which meant the cuts were less deep and less defined cuz the foam wasn’t dense enough to handle the cut (like making a sculpture out of Swiss cheese). The other company also didn’t line up their machine with the corners of the foam so the cuts were all out of line and it was only like 10-20% cheaper. I WILL say that Arrowzoom cuts weren’t 100% lined up, but very damn near close, like 99.8%. I would guess their tolerance is only 1-2 mm, but I will definitely be using Arrowzoom again, great value for money.Expanded almost immediately upon opening, but def recommend filling your bathtub and letting them sit for 30-60 min then squeezing them out and letting air dry. Avoid wringing/twisting too much as this may damage the fine edges. Also, avoid the dryer as the tumble may damage edges as well.Overall very satisfied and would recommend and buy again.Note: if you notice how some lines don’t line up, that’s cuz I used Arrowzoom right next to the cube, then the cheaper, less dense foam on the outside of that.

届いて開封したけど、説明の通りだとそのまま放置なのか、ちぎってから放置なんかよく分からず結果2日放置したけど、膨らみに個体差がでてしまった。でも部屋の角に設置したら、音質に変化は感じられたので満足な購入でした☆出来れば白も作って欲しい。
