SONICMAZE! Decorative Acoustic Panel Art: Sound Absorbing Lightweight & Micro-Perforated (3 x 3 panels, DIY fast installation)

Hundreds of dollars and a damaged wall later I am still not sure if it reduced noise from my neighbors. The description did not make it clear that it was designed to mount with screws. I made holes in my wall, but it turned out that the dry wall does not hold these screws as they come without plastic caps. Also, the metal frames that you use to hang the panels are dirty! They left greasy black residue (from the factory?) and yellow glue residue on my wall. The black residue did not come off. So horrible! If you do buy this product, see if you can find white plastic frames to mount the panels, or perhaps paint the frames first. Also, don't ruin your wall with screws! Use hanging strips, four medium strips can hold up to 12 pounds (this product is under 5) and they don't damage your wall. Horrible experience... Now I need to patch holes and paint over my wall :[

Installation was a PITA but it looks good, seems to cut down on some of the echo and reverb.

I got this box as a preview item. All I had to do was pin the template on the wall, screw the tracks on the drywall, and click the 9 magnetic panels on, Voila, 20 min. work!!! The company said: there are 30,000 tiny holes on each panel. Yep, sort of able to see it. The printing work is great. I hung it behind the TV, hope this will kill some of the bass noise from my neighbor. So far it looks very nice on my wall. I guess we can take them with us when we move to a new house for sure.
