Review on DEWENWILS LED Plug in Night Lights: Auto Dusk to Dawn, 360° Rotating, Directional Nightlights for Kids, Hallway, Bathroom, Bedroom - Daylight, UL Listed (4 Pack) by Angie Gonzalez

Works very well. They turn on when it gets dark and light up my hallway and stairs well so I can walk around the house at night without turning on the lights and waking everyone up. Since they are plugged into an outlet, the battery does not change. The caveat is that your home needs outlets in strategic locations. The only complaint is that the light looks like an artificial white LED and not the soft white I was expecting. I have a very similar model from Target that is in soft white and I ordered these as I needed to distribute more of these around the house.
