We bought two bookcases to fit in a long niche along our rec room wall. They fit nicely together in the space and look good. We rated the pieces four instead of five stars because a few of the holes for bolts were not aligned. This made them difficult to get tight and left (very) small gaps between pieces that should be flush. The most noticeable place where this happened is with one of the short vertical support pieces, which did not tighten to perfectly straight. But it is not a big distraction in the overall look.
