It works, but it's super annoying at night. I wanted to use it and go to sleep with it on, but it's still very bright on the nightlight setting and the light won't turn all the way off. It's also loud. The combination of the two makes it so annoying that I have to turn the whole thing off at night. I like the solid colors for day time use. The changing colors has a weird flashing effect, but the individual colors are nice.
