Anchors did not hold in the wall when weight was applied. When tightening screws dry wall anchors spun in the wall making it impossible to tighten correctly. Also had two screw heads snap off when tightening. Had to go to Lowe’s to get anchors and screws to actually hold the shelf in place. If you buy these shelves, understand that they will cost you more money as you will have to buy a pack of hardware.
