This is a gorgeous bookshelf, well made and sturdy.  In theory, it was easy to assemble, however, take my advice and assemble in a well lit area and play attention to ensure your cam lock screws are flush.  I did find that the cam lock screws could be easily over tightened since they didn’t hit a natural end in the well, and it’s next to impossible to correct the error because they have plastic inserts the cam lock screws go into, and when you try to unscrew them the plastic insert just spins.  Other than that issue, it was a breeze.  The instructions were clear (and funny!), well labeled parts, high quality material, beautiful design.  Very well priced.
