Overall this is a very fun car to use and would be great for younger kids (<10 yrs old). As it has features that not a lot of rc cars have. It can change colors and height modes so it can have the front up and back down or vice versa. It spins in circles and overall controls very well moving back and forth as well as up and down. It can also climb stairs. Would be fun for kids to play with as it doesn't just move back and forth but would provide different opportunities for kids to set up obstacle courses with.Packaging: very easy to open and get startedInstructions: very simple and clear instructionsUsability: very easy to controlTested only indoors on carpet and hardwood floors. It is very fast on hardwood and works well on carpet but hard to turn as the battery died more quickly when using on carpet....
