I have the device now for about 2 weeks and thus get every day at approximately 10-12 hours of operation about 5-7 liters of water from our new building, although the temperature is 8 degrees Celsius at the lower limit, where such a device may still operate. The unit is well made for its price range, and has a simple and no nonsense operation panel. That the fan is quite strong (and thus for a good air circulation makes) the unit runs relatively quiet. The water tank is easy to empty. The hose connection for continuous operation I have not tried it yet.
The first operation I was shocked that even after 10 minutes, not a drop of water was deposited yet, but that was probably because at the low temperatures the water only once on the refrigeration unit freezes, and is released only after the first Enteisungsgang. Overall, the dehumidifier has fully met my expectations.
