I'm in the process of building this item so I'll have to come back and update with photos, but so far this is awesome! Packs were labeled clearly. The packs will be marked with a big number, then "Lego" set number followed by order number, so bag numbers are 1 through 16 with 99665 being the set number, and order is .1 through .73 and there is also the characters in 99665.A through .E so far everything is here. It did ship TIGHTLY packed in too small of a box for the amount of bags, so the base plate was bent and cracked a little, but still usable. UPDATE! So I finished building the set, and it was pretty easy once I figured out the bags. The bags each are numbered 1-lego set #, 2-lego set #, 3 lego set #, etc. There are multiples of each number, and it's bags 1 through 16. That's how to sort them. Easy peasy. Everything went together like a typical Lego set, so very good dupe! I was able to "glue" pieces together using 100% acetone nail polish remover and a q-tip, but you don't want to glue every single piece or it loses its movability on a lot of pieces so be very careful. Only complaint (not anything WISH did wrong) is Doc Ocks arms (which you don't want to glue) fall apart easily. All in all. It's a 10 out of 10! [Source : Wish]
