Love this monitor because my granddaughter sleeps upstairs and you can hear and watch every move she makes. If she is fussing you can hear her on it. You can also take it from room to room. If you are cleaning, like running sweeper and its noisey you can connect it to the tv and keep an eye on her that way. When she wakes up now she will look at the monitor and say hi so you know she is ready to get out of her crib. It is a wonderful item to have. It plugs into the wall for charging and you can even take it to others house if you need to. I believe every mother should have one of these. It is a blessing for all busy mothers and fathers. I rate this at the top of the line.
