Product review (5 stars): Works great!!
EXCELLENT! I got this as a birthday present, and it works wonderfully! It has a usb cable so you can plug it into a wall block or you can use AAA batteries (2). There are 7 different colored lights, which you can set to rotate or you can choose one color and set it to that. You can also run the fan without the lights on, if you want to sleep with it running. It only took 3 minutes for the whole room to smell like the lavender essential oils I used with it. AWESOME!
