Received this yesterday and I am so impressed! It works very easily and exactly as described. When I come home after work I only have to press one button on my iPhone and my music or radio switches to the hi-fi.
My only criticism is that you can only paid one phone with the device at any one time, so if my wife wants her music on the speakers she needs to walk over to the box and press the button. Hardly a deal breaker but it would be nice :)
