Transmission and volume:
The transmission works fine. Usually, we make a habit of the highest volume level, but that does not necessarily have to be in quiet rooms. So I hear my sleeping, easily verschnupftes baby breathe now at this moment, a noise I'd heard may, if the computer should run (transmitter is about 30cm away from the nose, the receiver next to me on the desk). I can hardly imagine a situation in which the volume would not be enough - and then there are also the lamps. Their only drawback is that some foreign tones guarantee a flash, in addition to the cracking of the heating especially some sounds of sleep music. If you know that, but it no longer irritated (and our second son is fortunately - still - without this music, when the Great it was an important sleep aid). The two devices may not come in the way. From friends we know that there are other baby monitors that ensure that many parents of a development area, the neighborhood children can distinguish very well already screaming ...
Night light:
The night light on the transmitter unit is fine. Unless you come from a bright room itself, it is sufficient already to possibly sometimes retrieve the pacifier in the baby's room. In the bedroom, my light enough to breastfeed.
Battery performance:
The primary FR is now 2.5 years in daily use. Meanwhile, it runs in the evening for about three hours before it turned to us into the bedroom for the night on the charging station is (the whole night make it then did not). So far we have yet to detect any deterioration of the battery power, after the three hours, the battery gauge is certainly full.
Positive are also the long cable of the transmitting and charging stations, and "Remote Control" on the receiver part, inter alia, for lullabies. The intercom function has our children both more confused the Great finds now to play funny. A large range test we have not done, but both at home (from the 5th floor to the courtyard) and in holiday homes up to the terrace on the other side it has always served.
If you read some of the bad reviews, it seems to actually give Monday models. But since the manufacturer then obviously sends spare no fuss, I can not understand that you are lets the bad review so. For a "regular" device come to mind no negative points - full purchase recommendation!
