, , , the radio Gong 70285 of Heidmann when someone presses the doorbell. In other words - the device does exactly what announces the description of the product. Very positive is m. E. that the device can also be combined with a conventional front door bell. So you can connect the transmitter to an existing well Gong and then gongen Both. In addition, I was able to leave my brass bell, which alone is of course visually already super. Gong melodies are a matter of taste. This gong has the usual electronic tunes on it that I personally do not find really attractive. With me holding gongt Big Ben. So I am satisfied with the part, price and performance are m. E. in reasonable proportion. Enthusiasm would also no other trigger Gong with me and to be able to play all the MP3 songs I really need not have.
