I am not currently using these exactly as intended, i.e., on a wall: they are standing on my desk with my turntables and mixer; against the wall, but not fixed to it. I bought two and have stacked them on top of each other, one 'n' shape on top of another. The upper one has my only effects unit screwed into it (the recommended screws and nuts work perfectly). This means that the effects unit is at a perfect height while I'm mixing. Sitting on top are an audio interface and loops unit (held in place with blu-tack). On the lower one is my plug adapter with everything plugged into it, also held in place with blu-tack. It's a very cheap and cheerful solution to getting wires and cables off my desk and having a proper home for my effects unit. In future I may screw it into the wall properly, but for now I'm happy. They are very reasonably made for the price and I would buy more.
