Property me this Aroma bought humidifier to get a more humid air, with a side effect of aroma. The device is quite small, but what I like. It is also very quiet and the fragrant smell is very good effect. Unfortunately I have to give one star deduction, because this device does not even begin to humidify the air. Namely've a hygrometer at home and the display will remain more or less always on 30% but what very disappointed me. But I have to keep the unit due to the Aroma Diffuser and will now order an additional Lufbefeuchter me.
