Worked great right out of the box. The craftsmanship was outstanding. It does run so fast that it will vibrate off the table so don't walk away from it. This is fun to play with and an excellent learning tool for getting your kids interested in science.
This engine works beautifully! Not only does it look classy, it runs very smoothly and is quite entertaining.
I got this gift for my nephew and he loves it!
It is a perfect gift for children aged 6-12, its not your usual toy, the children get to learn new things and if they find it interesting, might want to know more about such things.
Very impressive little device definitely a showpiece to show intrigued visitors.
