I should say at the outset that the 2 bookcases we bought are a good value for the money.  However, this was our first purchase from Wayfair and getting from what came in the boxes to the assembled products was more difficult than I'd anticipated.  There were no written instructions, only pictures.  This resulted in rework.  What I thought were screw caps turned out to be integral to attaching the shelves to the uprights.  Also, the clips used to attach the trim to the uprights had to be redone because it was not clear which side of the trim they needed to face.  Written instructions would have precluded both these problems.  The screws protruding from the uprights look tacky, even with the stickers provided to cover them.  During the manufacturing process, providing a 1/8" countersink to each screw hole would have allowed the screws to sit flush and the white stickers would have been fine.  The first bookcase took 4.5 hrs to assemble, while the second only 2.25 hours.
