I have had great success with items from Wayfair for years.  I chose this product to fit tight space in a  closet.  
This shelf wasn't worth waiting for delivery - flimsy, swayed and did not inspire confidence for even a fraction of the weight/shelf.  The diameter of the clips was not great enough to keep all 4 corners of the shelf  stabilized, nor level.  The enclosed pieces to  zip tie shelf  to the wall were laughable.
