Subtle accent with its bamboo and frosted glass cover adds wonderful healing aromatherapy when combined with therapeutic grade oils. I appreciate the multiple settings to chose from so I am able to run the diffuser at night without the colored lights as a distraction to sleep. It does not take much water and a few drops of oil to produce hours of scented mist. The unit turns off by itself and is silent when active. My only disappointment is that the internal housing is plastic and I was hoping for an all glass unit to avoid plastic off gassing but the unit doesn't actually get warm so I believe that effect is minimal. Effective and beautiful unit
