Query: Waste of money

This is the worst waste of money you can get for your iPod. It doesn't work with digital radios that have automatic tracking systems, such as those built in Fords. It works fine on my Alarm clock/radio, but why use that when I have my computer on the other side of the room? If you're going to be staying in a hotel room, or otherwise staying somewhere away from your computer for a long time, you're better off just getting normal computer speakers. They plug into the headphone jack and run off the iPod's power. Not as portable, but they certainly work better.
