The Good: I've used this for two years and never had a problem with it. I've used it on my all my iPods and the iPod Touch with an AD2P link with my old Motorola cellular phone.The Bad: Someone runs a microwave in the building and you are there, the music stops and starts repeatedly until the microwave stops or you walk away. Doesn't fit well with the iPod Touch or iPhone models. You need rubber bands to hold them in.Note that you don't need this for iPhone 3G after Summer. So if you haven't purchased it yet to use the headset and iPod features, don't bother buying it.
