Although we love the look of our wall shelf, we did have some issues with the quality control which I have already addressed.  The unit came without the necessary number of screws needed to attach to the wall (we used our own). Also, the diamond brackets (2 of them) had very noticeable what we think are tape marks on them.  Tried to remove the marks several times with no success. Also the square 'plugs' needed to enforce the brackets so that the shelves don't come loose, don't quite fit.  I did bring this to Wayfair's attention and they have refunded a bit of a refund.
