BUT: the very short battery life of battery (3-4 hours), which strongly limits the mobile use, especially CATASTROPHIC NAVIGATION to select the mp3 you want to listen: it is only possible to switch from one mp3 to another, not from one folder to another ... you imagine the time spent finding the folder ... especially since they are not stored in alphabetical order but in the order they were recorded on your key or card !!! Under these conditions, use this soundstation can quickly become unbearable ... it only remains to use as radio or as an mp3 player docking station ... What a mess!
