Basically it was easy to assemble until I got to the door on the bottom shelf.  Several times I got it line up almost perfect, using the tool.  It just needed a little nudge. My little nudge turned into a bigger nudge and suddenly the spring flew across the room.  It's tiny, but I found it twice.  Still couldn't line it up.  Couldn't find it the 3rd time, so I call the manufacturer.  I thought I described it well, but they sent me a bag of parts I didn't need and only one that I needed.  So I carefully lined it up and zing, the spring was lost again. I gave up.  Not using the door on the bottom shelf.  It still works as a bookcase, but I really liked the idea of the shelf having a door that I could put thing behind that didn't need to be seen.  Oh, well.

Pros: Nice looking!
Cons: Couldn't get that door on properly.
