After the heavy rain we had water in the basement (2cm high on tiled floor). After we had removed it, the dehumidifier was used. He has been deprived of erstenTag the air 20 liters of water. It works great and is easy to use. Only the labeling of the display next to the scroll wheel could be better designed. It took me a few minutes, until I knew which direction I had to turn the wheel. The unit is great for the price. A strong buy recommendation !!!
