This is, rather inaccurately, catalogued as a toy. In reality, it is a pretty good pint-sized model of the type you remember from biology class. Good quality materials, nicely coloured, good representation of the human skeleton, accurate fit of parts. Some people will enjoy the 'puzzle' aspect, i.e. working out the proper assembly sequence and method, and racing against the clock to get it done, but most will simply leave the finished item on display on a desk or in a student bedroom. I feel the 1 star review also given here is unfair, because with a bit of effort the buyer could have avoided what ultimately was a purchaser error rather than a trade description inaccuracy. As far as price goes, anatomical models generally don't come as cheap as an Airfix kit, and against that backdrop this entire series offers good value for money for teenagers or adults. Not suitable for kids, in my opinion, not so much because of the subject matter but simply because these are NOT toys.
