It does what it is supposed to to without a glitch or hitch!
I have had my unit for about a week and am trying all kinds of essential oils in in it.... finding out what scents I like, which seem to help the sinuses and which my spouse doesn't like too! I have tried about a dozen different essential oils that I happen to have on hand. It runs quietly, a faint hum that is not at all distracting, and I barely notice the little beep when it shuts itself off when it runs out of water.
Looks: Right now I have the light band set on a teal color, but usually allow the whole rainbow to cycle thru. The wood grain finish blends in with my decor, so much so that a woodworker friend who came over for a visit had to feel it because he didn't believe it was plastic!
