RIO Chiba 512MB Digital Audio Player 28260102-001
I have this unit for a year and a half. It works perfectly, the sound is great, an alkaline battery (AAA) lasts 18 hours for sure, it is easy to use, the software is good and make its usage easier. <br /> <br />The bad is that I can't extend its memory more than 512 MB. But I have a lot of space already.
