The shelf itself is good. Well made and visually through the glass floors beautifully. The major complaint are the two screws for wall mounting. These socket screws I can not fully tighten, as the inner enclosure when screwing is "around" become and so could no longer be rotated. Neither pure nor out and were just screwed half, so I had to cut the bolt with a hacksaw. Here Phillips screws would be considerably higher. But ansonstren a good shelf.
