Query: Very unhappy....

I've had my Rio Forge 256 for 7 months. I only use it about 2-3 times a week no longer than one hour each use. Over the last couple months, I've been experiencing problems with my unit. More recently, it turns off for no reason. It sounds like a lot of people are experiencing problems with this unit. If you go to the Rio website, they have a Q&A of issues, I've experienced most of them. I'm still working with Rio to figure out a way to fix the problems I've been experiencing. This unit is made for active use and it doesn't seem like it's holding up very well. I'd recommend looking into a different brand if you're shopping for an MP3 player.
