Shipping smoothly, fast delivery. Item as described or expected. The wall mount makes a very solid impression. The installation is unspectacular, by anchoring in brick wall, holding. The boxes should be at least 13.5cm wide, then accesses the clamping mechanism. In addition, the speakers are secured laterally by means of small screws (is simply screwed into the housing). This allows them to not slip or tilt even when leaning forward. The system is not as graceful as an installation by screwing on the back of each speaker, so it's not hidden mounting, the impression is very good and stable. I have it taken away from me in white, because it almost disappears against the wall, is so unremarkable, despite the comparatively massive execution.
