Retailer reviews
Summarized retailer review data when available.
My grandson, who received this gift for his 12th birthday, was very enthusiastic.
Very nice LEGO dragster. My son is 7 and was able to put it together with some help for the small parts. What's really cool is the traction motor, which allows him to really play with it. The car is strong and can withstand some collisions.
Nice toy
Nice toy
This is a great set, especially for the price. My 5-year-old son was able to put it together almost entirely himself, but it is actually intended for older children. It is quite a large set and it drives like a dream. Because it is technically Lego, it won't fall apart easily, so they can really play with it as a car. The fact that you can also build another car with it is always a success.
What I like about this product: top quality and many possibilities!
