When opened box, the plastic bag with the metal connectors was open and we were missing two of them which hold the large screws in place.  The corners were uplifting.  The back cardboard had lines because of having to unfold it.  But the lines did not go lateral which would have matched up with the shelves.  Missing Part...  Poor Quality.  Very disappointed.  But not worth my time to try to box it back up and ship it back.  I will just make it work because I needed it now.
