I have purchased several of these because we have them all over the house and I absolutely love them. What I like most is that they are rechargeable so no wasting batteries. We have 2 in our hallway so now I dont have to leave the light on all night, these will just come on when you need them to and they seem to know when to go off. They dont even come on during the day when you go by, its like they know if its dark and you need them. I honestly dont know how we ever lived without them.
