BT Digital Baby Monitor 100 is a sound Baby monitor which includes: Parent talk back Three lullabies Sound sensitive lights Night light With mains leads or batteries for travel Out of range alarm plus more. It was my second baby monitor so didn't have much use so in good condition, has been stored in my spare room. I have tested it and it is in great working order, and still with packaging, instructions and new travel bag. (needs new aa batteries). Any questions welcome.
