The shelf pieces do not not seat flush. One of the long shelf pieces would not seat flush to a side piece with the cams. My husband disassembled and reassembled it several times and the shelf is 1/16 inch too short for the cams to seat it. He had to add two extra screws to get the board to seat flush. The stickers to cover the screw holes are a poor solution. There should have been plugs or inserts to cover the holes instead. There were not enough stickers to cover all of the holes. There were no extra screws, cams, dowels or other fastners in case of a defective one or missing one. After tightening all the screws the shelf still wobbles. We decided to keep it because I have wanted one for years and I didnot want to put my husband through assembling another shelf with substandard fitting parts, fastners and hole covering stickers.
