Okay, but there are better options
Honestly, not sure what I thought regarding the aromatherapy aspect, but since you just add it to the water it is hard to really say it operates any differently than any other humidifier.  As such, it works reasonably well and the changing colored lights are a nice addition.  However, as other reviewers have mentioned, even with the light changing feature off, turning on the humidifer engages a bright blue LED on the front.  You can turn it around or cover it up, but if you are very light sensitive and want to use it while sleeping, I would steer clear.  Also, the hole for filling it with water is pretty small, so cleaning it will not prove to be an easy task.  Overall, I would suggest a better (and larger) humidifer that you can scent with whatever oils you like just as well as this one.
