## Customer Reviews

### ⭐⭐⭐⭐⭐ Rollercoaster enthusiast
*by  on Reviewed in the United Kingdom 10 January 2025*

I wasn't sure if this would be too much for a 7 year old but he loves rollercoasters and building so figured we could build with him if needed. The step by step instructions were very helpful and after the first 2 simpler builds that were straight and a hill, my son was able to build this mostly by himself. He tested and manipulated the loops to get it working and then explored putting coins in the carriage to weight it as different positions and weights. It was really good fun and unintentionally educational. The cost was definitely worth it. As he gets older reading the book and the controlled experiments will be great. For now it is fun.

### ⭐⭐⭐⭐⭐ Excellent
*by  on Reviewed in the United Kingdom 17 October 2024*

My 9 yr old son’s favourite toy by far. Well made, instructed and lots of possibilities. Accompanying book is interesting and educational as well

### ⭐⭐⭐⭐ ok
*by  on Reviewed in the United Kingdom 15 January 2026*

parts can snap or a bit flimsy but overall its fun and a part are good quality just the track that lets this down
