Review (1/5): I would not recommend
Ordered three humidifiers, because the price was so good. One of the humidifiers was missing the water tank cap, the other one we tried cut off after 15 minutes or so. I could not get it to stay on. I did not notice a smell at all when I added essential oils. I think because the mist didn't go very far and would not stay on. The water tank is very similar to a humidifier, which I do not like. I would not recommend this humidifier.
