I just bought it, first day of testing and it already, this is perfect on paper but in practice it is another thing for the radio must circulate to capture the base works with batteries and can operate with a diet that is not provided, for my part is for use with the TV, then connect again the sound is very low even if I put everything thoroughly, and if you want to switch back to the sound of the TV must be disconnected from the database, only positive can be used as baby phone, and the headset can be connected with the jack to the PC or mp3 player.
