I got lucky with this one. Well worth it.
I normally hate to buy mp3 players because I feel that if you have one in your phone it shouldnt be so hard to find a standalone one that works and doesn't cost the same. Then you buy them and a reasonable price and they suck. This one doesn't suck. It's great. It does what you want an mp3 player to do and the battery life is LONG.
you take a chance with a used gogear.
Bought a used 12 dollar gogear for my 10 year old daughter because it was cheap. she loved it til it needed charged the first time and would not take charge. have several gogears and this is the first one to quit on me. get what you pay for.
