I was looking for a one step easy to use device to control my television and music system around the house no matter where I was in my home. I hated running in the house managing the music when I had guest over for a cook out or a swim. Audio Trix recommended Total Control System where you can control your audio and television system via smart phone or Ipad. I now have Pandora, Rhadsody, iTunes, Direct-tv and much more all at my finger tips. It is so easy to use my wife, who doesn't care much for electronics, can use it. I love it.
