Query: This little thing is cool...

I bought this MP3 player for my 9 year old son. It has a couple of quirks - like sometimes it freezes up on us and I have had to pop the battery out to get it re-started. It's really small, lightweight and easy to use. The instruction manual, however, is VERY basic and it's been trial and error figuring out how to download and edit songs. All in all, I'm pretty satisfied with it for the price.
