I usually have a thing against night lights. I'm the kind of person who wants the room to be as dark as possible when I sleep, zero-light is the best. The only place where I sometimes have one is in a place like a living room, so that I don't trip over stuff if I need to get up in the middle of the night.
That being said, I need an excuse- like a small child sometime faaaaaaar in the future- to buy one of these. So cute!
