I got one of these for myself, my sister loved it so much when she saw it, she ordered herself one and a couple more for her friends! The glass bell shape of it and the lights reminds me of beauty and the beast. The diffuser works great, lasts a few hours continually, and then shuts itself off when empty. I use it every day, sometimes all day. While it may need refilling more often than my other diffusers, I still find myself using this one the most. It doesn't need much fragrance added either, a couple of drops seems to last until its empty, sometimes its not even necessary to add more oils with each refill. I very much recommend this for anyone, I plan to buy another for our basement. One alone fills the entire main floor.
