Have the equipment purchased on the basis of good reviews and was not disappointed! I use it to dehumidify a basement room. The noise is not the criterion, but the unit is running so quiet that you could also use it in inhabited rooms. Nothing clatters or rattles. However, the compressor course caused some running noise, so for sleeping quarters the subjective perception must decide whether to live with it, or can better sleep. The dehumidification performance is quite OK. One should not expect only that the maximum value of 25L per day is achieved in any case. I'll be about 10 -14 L / day but this is affected by the ambient temperature and humidity conditions. In the accompanying description, a corresponding table is to find where the expected performance is described in certain operating points. Overall I am very satisfied with the device, the price / performance ratio.
