I received one of these racks from a friend who was moving. Frankly, I don't know why she got rid of it. I've used this rack over over 6 years now with no problems. I've used it for tight-space clothing storage, potted plants, and, of course, media storage.
The kit sets up relatively easily, though you may have to re-set the plastic pieces a few times before getting it perfectly right. After a while, you may also find the racks get stuck and need more force to remove them. These are really my only complaints in six years of using this rack.
The way this set is made, you can set it up to meet a variety of needs, including different heights to accommodate books of various heights. I once had this set over a relatively tall desktop PC for storing software CDs. I even set it up once upside-down to hang below a loft bed! Talk about versatile!
One of the best things about this rack is that it collapses down very well for moving. I've marked it down for value for price only because it is a slightly expensive item, but for its ability to be used for so long (who knows how long my friend had it before!) and still work well, this is well worth the buy.
