Beautiful product. Had no issues building it (although it's definitely a two person job) and was supplied with a spare for each type of screw. Only reason it's 4/5 is that there's a lot of visible screws and joins (sides of ladders, underneath shelves) - it's not terrible and generally I don't notice them but with other brands they can supply covers that help hide these.

Overall very happy with the purchase, perfect for storage in a small room! Would definitely recommend.
