I used this absorber in difficult room, it sounds great now.
The difference in sound was immediately obvious, and product looks exactly as shown in the pictures. The product is worth the price.
I really liked that corners on the back of the absorber are removable. So you can glue them back together or leave it if you prefer like you see it on the pictures of the product.
The front finish, it's like some kind of plastic instead of wood. But I don't mind it too much.
Note: I bought the t.akustik Akustik-Kleber, but it not worked for me since that glue takes too long to dry, and it is not made for absorber of this weight. I used "UHU the all purpose adhesive" that i bought in local store and it worked perfectly.
Just for the info; I glued foam on brick and dry wall (ceiling), and I didn't even use too much of glue.
