We opted for this baby monitor, because we have been recommended by Avent. I must say that I am very happy with it. There are several from the series, for me the varied functions were decisive to buy exactly this variant. As allerwichtigstes I feel the link light to indicate that the parent unit contact with the baby unit has not that at some point the contact breaks and one thinks that the baby is sleeping calmly. Good is also the option to adjust the sensitivity, from which the transmission starts. Depending on whether you want to hear only cries or wants to listen to the baby's hiccups. It is also possible to let check the vibration, if you ignored the noise. In addition, the volume is indicated in the baby's room by several blue lights. So I can take a shower and "see" whether the child is crying, because I would not hear it through the noise of the shower. For a low-sparking reception there is the possibility the Eco Mode on, this, however, reduces the range and in our house does not work so well. The parent unit is charged via a charging cradle and the baby unit is permanently attached to the power, but can also be equipped with batteries for a power outage. Batteries are not possible or are not loaded. What I also really great find are the functions of the starry sky and the playing of melodies, they can either on the parent unit or the baby unit and also switched off. After the nocturnal silence, I put our child back to bed and place the colorful starry sky, then he sleeps better after a. Also there is an intercom function, so that parents can talk to the child. Although this is not yet important, but perhaps later if the child can already speak.
