This is a great little device.  I wanted something to use on my boat (that has a mini input jack) to play Pandora wireless.  I had been using a mini to mini cable, and had to leave my phone where my stereo was.  With this device, I am able to turn blue tooth on my phone, press the button, and poof instant blue tooth connectivity.  Gotta love Pandora...
