Poor craftsmanship. The plastic used for the shoe rack hinges are very week and slit instantly in several places when screwing in the screws (by hand).  Plastic nubs that attached the shoe rack to the wall and allow it to rotate, split and popped out the second time the shoe rack was opened. Entire unit was very wobbly and is unsafe for my young daughter who is just learning to crawl and likes to grab anything in reach.
