The aroma is amazing. Using pure essential oil and not water soluble like in the humidifiers makes the vapor much stronger, a few minutes running and my whole house smelled like a big ball of frankincense. The colors fade from one to the next, and the dial sets how much vapor you want. It does make about as much noise as an aquarium air pump, I suspect that's how it works. My friend has an ultrasonic humidifier and it is silent, but he has to use water soluble hydrosols and can't use pure oil, so I like this one better. Plus it's actually wood and glass as well, not plastic, very stylish.
