Query: Not worth the hassle

This is my first mp3 player so wasn't sure what to expect. For the first day I was happy with how easy it was to use... then the problems began; radio presets don't work, battery doesn't stay charged very long,radio recpetion's not great, has mysteriously turned off by itself a couple of times. I'm taking it back to the store and will try to find something more reliable.
