So, from the capacity I'm not excited, I'm sure we could have taken advantage the volume better: 80ml are just not much. However, the measurement is better, which is attached to help, always add the correct amount. As scent diffusers that thing works terrific, it actually smells even with 2 drops of essential oil very quickly across the room pleasant for the scent. I have no remains of the oil in the tank and the resulting residual scents noticed at the next filling (also very good!).
For humidifying the room the thing is, however, too weak. I sit on regularly turn up the volcano and has occasionally resort to additional tools. Since it is next to my bed, which is the room air also relatively, for me it is pleasant:]
The volume of the volcano is mainly due to the fan. The bubbling of the water is to me almost too quiet, I hear it almost. Although I feel bothered me fast noise, the fan of the volcano is so monotonous that the sound disappears quickly. Sometime during the night, it then turns off automatically.
The light show is fantastic, but is not fully appreciated when it is bright in the room (it is too weak). In the dark, it's beautiful for it. My favorite color is deep red, but you can hold all transitions when you press the little buttons at the right moment. When the gradient changes from one color to me is a bit too fast, but that's probably just taste Sachtleben.
