This baby monitor's great: clear sound, no interference. Ability to adjust the sound very low (it avoids startled the night .....). Small pilot "soft" integrated. The melodies of lullabies are pleasant. The temperature of the baby's room is displayed on the parent unit (a plus in both summer and winter) with alarm when the room reaches extreme temperatures (not super helpful since the alert thresholds are too high: 38 °). The only catch is that the baby unit does not charge and can only be used on AC power. The more the more: you can mute the sound of the parent unit (alarm position) and this one make a small beep when the sound in the baby room reaches a certain threshold sound (it avoids waking up to chirping less) .
