Review (5/5): It works just like it says it would!
I thought that perhaps the price was such a bargain that I'd better order a an additional more expensive item to be sure of results. I have seasonal allergies and use diffusers with certain essential oils to clear my breathing. This last longer. The air flow is very steady. I can lower the amount of vapor or raise it. The lightening is beautiful with the addition of the Himalayan salts! I LOVE IT!
