Pros and cons
What we like
- 62 LEGO elements and a 64-page idea book come in one kit
- Builds moving models that work with a hand crank
- Teaches axles, cams and cranks through play
- Papercraft sheets add decoration to each model
What may bother
- Only 62 pieces, so the models are small
- Needs patience to follow the gear steps
- Papercraft parts are fragile compared with bricks
Our verdict
84 / 100Perfect for a curious kid who asks how things work. It teaches mechanics and still feels like play. Choose a larger set for a child who wants a big display model, or a simpler kit for under eight.

The score does not depend on the guide. 60 to 69: average gift. 70 to 77: good pick. 78 to 85: safe bet. 86 to 89: favorite. 90 and above: the perfect gift, a label reserved for excellent products that customers like, one winner per occasion. In a guide, the score for the recipient combines this score with the place in the ranking. The budget is an indicative range: the exact price is shown by the store at checkout.
