The Babble Band has 3 different monitor modes: Audio mode allows your to hear your baby straight from the nursery; Vibration Mode allows your to feel when your little one is crying without the audio; Sound Light Mode allows your to keep audio off as sound activated LED lights provide a visual cue when there is a noise in the nursery. The recharable battery gives you 8 hours of continuous use and the base unit doubles as a recharging base for the band. Why buy me?
