Ashamed to provide a toy at this price, with such a deficiency: the battery charge is limited in the best case 15 minutes. In other between 8 and 10 minutes (which my case). When the access to this famous battery system (it must be removed several times a day!) It's two Phillips screws that are in business. 0 péromé a sytem for thirty years ... Not these two problems make me regret this purchase, and discourage potential lovers.
