Query: Utterly useless, the wood bows and the shelves fall.

I don't need to say more than that. The side wood is not straight, it bows outward and the pegs are too short, so the shelves literally fall off the pegs and your DVDs go crashing to the floor. This thing is terrible and a waste of money, don't buy it.
