Works ok when you first plug it in. Once you unplug it and try to use it again, not so much. I can no longer us it as a radio tuner; it just plays my music files. The only way I could get it to work again was to uninstall the app and reinstall. Of course, it stops working again when you unplug it. (Im using an iPhone 4s). Good luck finding online support! JUNK!!
