The bookcase looks pretty good all put together, but upon close inspection you can see edges don't line up.  This thing was a PAIN to put together.  Put your patience hat on.  Worse than Ikea furniture.
I guess you get what you pay for - it's an affordable, modern looking bookcase and just what I needed for my space.  But be warned about the quality. Also, I'm fairly certain there was fiberglass dust on the shelves that arrived in the box, which made me a little nervous.  I would recommend wiping down the pieces with a damp cloth.
