It is positive that can be seen immediately and from afar, how full the tank. Dehumidification and ventilation are good, Trotec but very good. And that is cheaper, though it is much more powerful with 650 W.
Negatives: there is no indication of the rel. Humidity and the onset of the water tank flutscht not as good as in the Trotec devices. Sometimes you have to knock against it, so that the green LED indicates that the device switches on again.
