This shelf looks great and displays the my books and other various items really well.  It's more for decoration than storage though.  I can fit about 10 average sized books on each self, but that's it.

The assembly is definitely a pain.  Especially drilling it into the wall.  The instructions are a bit odd, but once you figure it out and get it all set, it's a nice shelf to look at.  A great addition if you live in a townhouse or apartment.
