Great quality , and instruction were fine. Purchased for 8 year old who likes this kind of stuff. She enjoyed taking apart a naming the parts, had trouble putting together but with a little help we got the human together in good form. Had a fun time and have 2 more grandkids who will enjoy it as well. Again quality of model is great not cheap hard hollow plastic parts but solid softer PVC , detailed organs that fit together well , some have alignment pins to set in place.
