Bought for help, my children still tend to misplace their MP4 just before the great journeys ... A real catastrophe! This is not even a toy that makes me just feel a lightweight prototype just to show design ... Do not look anything like the picture (there's got to be a prototype which they are applied for laphoto ;-)). Navigation very difficult, impossible to go back, forced to switch off and on each time you want to exit a menu. Do not play MP4 contrary to its description might suggest. Instructions in English "Chinese" only. Taking unknown charger (USA can be ???). Null at zero.
