Product review (3 stars): Pretty cool actually
PROS
It's really simple to use
Can choose lights or no lights
not too noisy
cool to watch
Used it in the car (FITS DRINK HOLDER IN CAR)
Used it on my desk at work

CONS
not sure if it works all the time. (the spinning piece sometimes picks up the water, and sometimes doesn't, not sure if this is important for the oils to be dispersed.
Can't see the mist

Summary:
Can't really go wrong for $20. Would like to hear from manufacturer to know if it is really working or not.
