Perfect for your 2 similar aged children who love a little competition, noise (track is noisy, plus you gotta dodge expelled cars) and too much fun disguised as havoc! The kids adore this game, nothing is better that this game settler! You can have teams Darby like games etc. Their minds and your fine China are the limits! Totally beloved and always either an argument ended or beginner, how all toys are. But if you get to just sit back (at a good distance), sure it's a bit loud, the crashes make you worry for that lamp but none of that beats the happiness and laughter.
With my children I bought loads of hotwheels cars and let them pick 1 a time, and I used a paint pen to mark the bottom of each car. Never an argument, then you can also take a better guess at where the lost ones are. So much fun and laughter and excitement. It's like a real destruction Darby or similar. And the kids love it. And I love their constant laughs
