The Belkin TuneCast worked okay for the first couple weeks I had it. After a while I couldn't get it to turn on no matter how many new batteries I tried. Even when it did work, the sound quality was not very good. I bought the Griffin iTrip and found it had much better sound quality and was easier to use than the Belkin TuneCast.
