A little nervous and solid racing car that consumes a lot of battery!

This remote controlled car in the colors of Ferrari is solid, the plastic is thick and despite the shocks against walls or chairs, it seems to resist. The aspect gives confidence, this toy is not "junk".
The car is controlled by a wireless remote control with 4 buttons (forward, back, left, right), this is probably not the most easy to maneuver for a small but everything reacts well and quickly. The car rushes, it is fast and runs well.
Bad surprise anyway, the car request 4 R6 and remote control 3 R6 (not included)! Could they not put a 9v battery in the remote control instead?
A good remote controlled car that I advise you ... with a purchase of rechargeable batteries if you plan to use it often!
