Essential Mist Starter Kit, Lavender And Almond Blossom, 0.67 Oz Bottle Contains natural essential oils. Once started, the device automatically shuts off after 8 hours, restarting at the same time the next day—8 hours on, 16 hours off. Battery operated for placement anywhere. No water needed as oil diffuses into a mist through microscopic holes in the vibrating plate. Three intensity settings for ultimate fragrance control. Each refill lasts up to 45 days at the lowest intensity setting.
