I almost marked three stars instead of four, so a bit generous.  We put together three of these bookcases.  It definitely went better after the first one.  You need to learn as you go, since the instructions are not fully explicit.  One of the valances at the bottom of the bookcase arrived with the thin laminate coating cracked, but not very noticeable; just an indication that these bookcases are pretty easily damaged, being particle board.  But they came together well and are serving their purpose keeping books from the dust in our basement.  That's what we wanted.  They're probably worth a bit less than they cost, but then there's the free shipping, so ok I guess.
