The best and most amount of storage space for your money.  I looked at a lot of different DVD/CD Walls racks, and this was the best bang for the buck.  Instructions aren't too challenging, but not the most consumer friendly either.  Took me about an hour & a half to unpackage and build the whole thing.  I too had minor problems with nailing the 4 back panels in line with the thin vertical wood beams.  Overall though, very, very pleased.  Looks great (and impressive) covering a large wall space.
