Query: Don't bother!

I bought this thing years ago when it was $100! it's so crappy, I can't believe they still sell it. You have to be within a few feet of it to get it to record. I bought it for lectures in class, so that was aggravating. The sound quality is awful. If you're willing to go to a professional sound studio digitally to separate what you wanted from all the background noise and static, then maybe you'll like it. I could never get the computer software to work, so I couldn't upload recordings onto my computer. Not that I wanted any of them after I heard the quality. You can get a much higher quality recorder with more memory for just a little more money. Just take the time and shop around.
