I was immediately annoyed at having to put the bookcase together because it came in what seems like 100 pieces.  The instructions was just small pictures of the what numbers goes into what letters.  It was pretty difficult to see what goes where. They should make the pictures larger as it'll be easier to see. I have two screws that would not fit at all but it was way too heavy and too many pieces to return so I made do and try not to put anything to heavy on it.
