These are quite nice and also sturdy. Only complaint I have is that I bought a couple of these, and on one of them, only one of them, it was difficult to get the hidden mounts to go into the holes. I think it was probably a manufacturing defect thing. Also, on that particular one, it wasnt as level as the other. Not a show stopper, but if you need a perfectly level type of mounting situation, I would be careful here.
