I made the mistake of ordering 3, took a total of 10 hours.  Will never do that again, only purchase items that are per-assembled.  Makes the closet look better than the open shelves that I previously had.
Disturbing that some peaces were packaged damaged, because the external packaging was perfectly fine.

Pros: Look good
Cons: To many pieces to assemble, not worth vrs the $$$ I paid for them.
