This bookcase arrived in 4 days!  It is very heavy and I had to unpack it on my porch so I could bring it in piece-by-piece.  I'm 70 yo and I assembled it on my living room carpet and then moved it into my home office. All pieces were in good condition and everything was there.  The instructions were clear and assembly was straightforward.  The instructions suggest two people but I assembled it myself with my wife helping to align the back. The case is rock solid.  Its true the back is flimsy but it is made out of 1/8-in plywood held on by screws, others I've bought are cardboard held on with nails.  This bookcase is exactly what I was expecting.

Pros: Solid construction, quality veneers on particle board
Cons: Can't think of any, I really like it.
