I skip now to respond to all functions. The songs, the intercom function, and the nightlight are functions that are okay, but do not need. The 5 songs are okay (which indeed would be better to be able to feed his own songs to the computer), the speakerphone function works, the night light is a little weak. But now the important. The ECO DECT function because of the radiation, the temperature display and the actual baby monitor function and the size to take home in the garden or cellar were decisive for us. And all this makes this device worth five stars. How Schubeck would say now: Wos wot do complain! And after many complaints of the faint sound: We did not find. We wake up in the night immediately. Even while watching TV or when we have guests, we have no problems on the baby monitor to be attentive. I think that people issues are either set the machine incorrectly (you can adjust for both parties, sensitivity and volume), or these people make the device too far from the child away, or at a party or Mega-action film you should shut Music make a little quieter! Worth five stars. Point.
