This bookcase was pretty easy to put together and, from a distance, looks really great.  However, up close, there are definitely many imperfections.  The tacks used to hold the trim in place show, and the veneer is chipped away in several places.  I ordered two of these, and both exhibited the same flaws.  I also ordered to of the 72" version of these shelves and was disappointed that the stain on both of the 36" shelves was very dark (almost black), whereas the stain on the 72" shelves was much lighter.  I couldn't really see the grain of the veneer on the 36" shelves, but could see it on the 72" shelves.  I preferred the lighter color and wish the smaller shelves matched the larger ones. 

At any rate, these shelves really do look very nice, for the most part.  You don't really notice the difference in color once the books are on the shelves, so that's good.   Just be aware that they won't be perfect!
