Prone to cracking, made worse by the sloppy pre-drilled holes.

The top of the bookcase was never drilled, a nail was sticking out on the side, and the crosspieces in the back were misaligned

My only real complaint is that the holes are not drilled into the top, and the screw holes were not cut as deep as they should be, so several screws did not reach as deep into the top as they should, leaving it a bit too loosely attached

One shelf cracked while screwing it in it seemed as if the hole drilled for the screwed to follow may have been crooked
