We bought three of these to stagger for photo displays.  They are decent quality and look great hanging.  Unfortunately I don't think the hardware is very well-made.  We had a hard time hanging them and one of the screws broke off into the wall!  Disaster ensured with trying to remove the screw, and eventually the hook on the back of the shelf also broke.  So, now I am ordering a replacement shelf.  I think the product is good overall, but hardware seemed a little weak.  Or perhaps we just got a bogus set of screws.
