Query: Rio Carbon Pearl 5 GB MP3 Player

Hard item to review. It has lots of great features and pleasing design , but I had to send two different players back for shorting out and becoming unresponsive. That said, my husband hasn't had a bit of trouble with his Rio Carbon, so I decided to try a third one. Three weeks in and my 6 GB Pearl is doing fine. I'm keeping my fingers crossed
