Q: I've had this mp3 player for a few months now and really like it. It's very lightweight, easy to use (I saw from the reviews here to format it before attempting to add music - that's the only thing that would've been unclear from the instructions), good sound quality. The battery really does last a long time if all you're doing is listening to music, which is mainly what I do. I'm very satisfied with my non-conformist (ie non-ipod) mp3 player! Saved myself a little money and don't look like everyone else out there.
A:
Positive
