Rdutuok 12 pannelli acustici, 30 x 30 x 1 cm, pannelli acustici ad alta densità, per studio, studio, trattamento acustico e decorazione da parete (verde)

I chose these tiles partially for acoustic treatment of my space and partially to serve as a rudimentary green screen background for improved background separation during video calls. I am happy to report that they serve both purposes as good as I could hope fore.The only thing I observed is that the tiles themselves are not necessarily as exactly square as one who has worked with terracotta or porcelain tiles. This means that they may appear slightly misaligned if you take them off the stack and rotate one by 90° or 180°. The best way to handle this is to keep the stack of tiles untouched and mark which way is "top". Then, only fit them in the same direction as they were on the stack without rotation.But the above is really a minor issue, it is only noticeable from really close, and does not detract from the overall experience. I am completely satisfied with my purchase.
