So the quality of this not great, but good enough and they look nice enough on the wall. However, the bracket holes are not spaced at 16" intervals. WTF? I'm not sure who designed this thing. The molly plugs that came with it look OK, but to play it safe I used a cobalt steel drill bit and made my own holes in the bracket. Easy enough with some wd40. My other pick with this is that the screws to anchor the shelf to the bracket are black and and very obvious... they should have supplied some kind of cap.

These floating shelves look great and were easy to install. The invisible brackets give them a clean, modern look, and they feel sturdy once mounted. Perfect for adding storage or décor in a bathroom, living room, or bedroom. Great quality for the price.
