Query: Sansa Shaker MP3 Player

This is a really nice mp3 player with a clear crisp sound quality. My daughter really loves it. It is nice to have the option of either using the ear buds or just playing it without. However, the battery life doesn't seem to last that long (3-4hrs continuous play) therefore I would recommend chargeable batteries. I would highly recommend this to anyone because you would be happy with this purchase.
