Overpriced garbage. Shelf is made of MDF (basically pressed cardboard dust and glue). Weighs over 200lbs, and has a weight capacity of only 22lbs per shelf. Shelf supports were PLASTIC. Although to be fair, the mdf is the weak point. 
More difficult to assemble than it should have been. If I could go back in time, I would have just bought some wood and made a shelf instead. Would have been stronger and cheaper.
