Our baby monitor is now in use since 1Monat and generally I'm satisfied. As mentioned often, this is babyphone quite quiet and for people who are used to analog baby monitors the sound level is certainly getting used to. Generally considered the baby monitor easy to use and the battery of the parent unit holds a long time. With volume and Sensibilitaetslevel you have to play safe at first something to fit his needs. In Eco mode, it seems a bit insensitive and zeitverzoegert, but may also only have been a unique experience.
It was important for me that the radiation exposure to my child is as low as possible, because in this day and age with WiFi and cell phone of daily life very "loaded" is. Unfortunately, you can as a consumer this criterion is not really check and you have to rely on the reviews of a more or less objective Institute. And a baby monitor a la panacea (ie HEALTHY, abhoersicher, low radiation, sensitivity, vibration and volume as with analog set) is not according to my research on the market.
