Despite everything, there are also a few negative thing. The reception between home and children is complicated by a reinforced concrete ceiling. This has been around even small interruptions of a few seconds. However, the connection is immediately automatically restores. Unfortunately, in the active time is always a slight noise to hear the faint sounds distorted. A loud crowing comes but over quite well. Vibration and warning light in the Parent Unit to help the baby noises to draw attention when the volume is turned off. Overall, the sound quality could be better, however, it is not necessarily the value for money.
I forgive three stars for this set.
