The steam feature is neat, though it is mostly for looks. It is pretty cool at night with the led lights and the steam/smoke on. Speaking of which, the lights are bright. I can stay outside later without backyard lights. Also, the batteries are long lasting (and it comes with an extra battery).
Overall, this buy was a big win. It was not the cheapest rc car I could find. Though, the value and utility of a tank makes it easily worth it.
