I was looking for an mp3 walkman music to accompany my pool lengths. I let myself be convinced by the competitive price of this product and the many rave reviews. As for the positives: the sound is very good and the device is very easy to use with direct loading of tracks in mp3 without intermediate software. By cons: the same button is used for multiple functions (eg front / rear = Volume - / Volume +) and it is impossible for me for several months to adjust the volume, I always skips to the next or previous song. Moreover, after turning it on, I can no longer turn the player who restarts automatically after a few seconds of interruption with flashing LED (for the same reasons as above, the button does not "respond" not) and I forced to let out the volume up battery drain (I lock the drive in a cabinet). Anyway, I do not know if there is a flaw in my own copy, but in my case, it is disappointing mp3 and if it again, I would skip, despite its attractive price .
