## Customer Reviews

### ⭐⭐⭐⭐⭐ Fun and challenging
*by J***Y on April 1, 2020*

This is a great set, but will require about 4-5 hours of time to put together. The instructions are easy to follow, and the pieces fit together well. But, this is not for a beginner at building sets.

### ⭐⭐⭐⭐⭐ I Nailed This Gift!
*by V***L on April 12, 2018*

Awesome! My roller coaster enthusiast, nine year old son LOVES this! I don't think he could have put it together by himself, but it became a fun family project. My three year old daughter also loves watching it go around! I think it may have become a permanent addition to our house.

### ⭐⭐ Missing pieces
*by S***M on March 16, 2019*

I bought this as a gift for my son. About halfway through, we discovered that it was missing essential pieces. So we couldn't finish putting it together.
