Love the general quality of the fit and finish. Two things that need to be addressed  one horizontal piece over the right-side hexagon had miss-drilled holes - they were 34 to 1 inch too far left, and I had to drill correct holes and cover the erroneous ones.  The other thing is no mention in the instructions, words or images, of the fact that the upper and lower supports of the hexagons are actually 12 to 1 inch offset from the depth of the bookcase in general on one side, and all those pieces need to be installed so that offset is all in the same direction for all 8 pieces.  Otherwise these are great.
