This was a very inexpensive bookcase, and we got what we paid for.  It was surprisingly difficult to assemble, in part because the screw holes on the front of the base piece were almost non-existent.  Even after the base piece was screwed together, the front of it was warped.  Fortunately, it is at the bottom of the bookcase, which is going in a dark corner, so no one will notice.  Adequate for the purpose.
