Product review (5 stars): Love it!!
I love this little thing! I've only used it today, but AAA batteries have lasted all day, and the scent permeates my little office! I'm using Doterra EO's and I used quite a few drops, but seems perfect to me. Glad to not have to use water to make it work in my office space. Rotating lights are pleasant but turn off if needed. My boss even likes this little dude ;)
