Good quality pieces.  Easy assembly.  Look great.  So why 3 stars?  The full height plastic strip that goes up the middle of the back boards is not color matched.  I bought 6 cherry bookshelves and this piece (which is very prominent) is light grey.  Also the plastic caps that cover the connectors are light brown.  Biggest issue is that one of the top board pieces came missing two of the four inserts that the 'three in one connectors' screw into.  Have not connected with the manufacturer yet on that issue, but basically can't assemble this unit until resolved.
