Query: Wow - works great!

I was amazed how well this worked. Sound is as good as it can probably get through one of these. It's kind of big physically (twice as big as my Sansa Clip) so that was kind of a pain, but excellent sound.The first one I bought had a bad connection inside so the audio cut out. Could not figure out how to get it open, but now that I have a new one (which works perfectly) I'll crack it open one way or another.
