The Glow & Go provides ultra clear, private audio monitoring of your little one. As you baby travels through his or her busy day, so does the Glow & Go Monitor. From nursery to playroom to kitchen, there's no need to plug and unplug over and over again. Just set the portable unit near your baby and see and hear sounds on your portable receiver from over 400 feet away. This set is equipped with two receivers so two people can use at the same time in different locations.
