The positive reviews on Amazon have led to the decision to purchase. The device is visually inconspicuous (about Design can argue) in "electric" and white is not yellow. The decisive criterion is a mechanical humidistat. This is very sensitive to adjust. If he turns off the blower is also. A possible power failure does not matter. In order for the device to be controlled, if necessary, a time switch. I use the device in a basement, sweating through the dew point at high humidities. I have succeeded in a few days to improve the air noticeably and dry damp areas sustainable. Currently, I am looking for an optimum balance between power consumption and humidity. It helps a lot that the humidistat is set very sensitively. Then the unit is quiet and peaceful to do his service, you just have to regularly empty the water, or derive equal to a drain.
