Query: Would Be A Great Product If....

...if the volume wheel didn't break so easily. I first got my first Rio Carbon for Christmas. Exactly one week later, I've got it in my pocket during school, I pull it out sixth period to find that the volume wheel has been pushed inside the Carbon, making it impossible for me to change the volume. So I take it back. This time it only takes me 5 days, and viola! Volume wheel breaks again. It fell out of my hands 5 inches above my desk, and the same thing happens. I don't feel like returning my MP3 player every week, so....I'm just gonna get a refund and buy myself an iPod.
