Just got them set up to give to our Grandsons. I am so excited, but heads up, read the directions as to how to maneuver them. We almost broke it just trying to see how they work. But so excited to give it to our 7 and 4 year old Grandsons. They know more about remote control stuff more than Grandma and Grandpa. !! Again, so excited, there awesome!!! P.S. Had fun teasing our 1yr old cat, it was too funny !!
