Poor advertising of Carrera

My Sohnemann has become a Christmas desired remote controlled car and get this part of the grandmother. At first it was really fun and it looks great too. However, the battery from the start was really fast empty (now have a car of Dickie, the battery lasts estimated 3 times as long).

After about 5 times Laden, did on the car nothing more. Had only suspect the battery is empty and the Fernbedinung have a newly cleansed, but this has unfortunately not helped.
This problem is probably happened already often in cars from Carrer. How have returned and reclaimed the money and brought a car from a different manufacturer the car.

After demm I now have often heard of such problems, I can not make purchase recommendations for this vehicle.
