Ultra Cap UA5372 36-Inch Wide by 12-Inch Deep by 85-Inch High Six-Shelf Open Shelving Unit, Grey

I ordered this product to use in my garage. When I received the boxes, the nuts and bolts bag was missing. It took two phone calls and 3 weeks to get the parts. We looked at the directions but the parts in the box didn't match the instructions contents list. The instructions were also not clear at all. The worst part was that the assembly process took 3 and 1/2 hours. This was due to the poor engineering of the product. The clips just rest on the frame so that when you push down one side of the shelf onto the clips, the clips on the other side would fall off. The parts do not lock in place, so I am afraid the whole thing will collapse.
