I Ordered the Absolutely Insane DEERC Amphibious Remote Control Car for Kids for the Grandchildren to Play with when they visit. While the DEERC Amphibious Remote Control Car is advertised as a Gift for Boys & Girls in the 5-12 Year Range, I would Suggest 11-16 Years Plus, Controlling the Car is Very Erratic in Operation and Difficult to Control by the Young Hands of 7 Through 11 Year Old's. I am sure that DEERC Intentionally Built the Erratic Behavior of the RC Car for the Pure Fun Factor... It is Very Exciting! While the Absolutely Insane Radio Controlled Portable Mini RC Car with its 360° Spin, All-Terrain Tires, & Waterproof Design Wasn't really a Perfect Toy for our Younger Grandchildren, it is a Real Hoot to Drive for the Rest of Us!! The Included Car Batteries Did Not Disappoint, Run Times are Excellent for such a Small RC Car. The DEERC RC Car Set Included Two Sets of Batteries, Tires, The 2.4GHz 4WD Stunt RC Truck, Radio Controller, & Tools. Just add Three "AAA" Batteries for the Controller, Charge the Included Car Batteries, & Go. We have no Intension to run the DEERC in Water, We do run it on Wet Ground, it is nice to know that the Electronics are Safely out of the Way in Their Water Proof Compartments. For the Older Children I gave the DEERC Portable Mini RC Car a Full Five Stars Across the Board. The RC Car is Durable, Easy to Use, Reliable, and a Lot of Fun to Play With to Name a Few of them.
