The device runs with me for 4 weeks in the laundry room. It also keeps at low temperatures (14 ° C) the Luftfreuchte at constant Luftfreuchte (with me 45%). The unit is very quiet compared to my last of Einhell and easier. So in the bedroom I would not place it but in workrooms with noises in the basement and mE hardly aufallend. The water collection tray is something hakelig that could have been done better with a brand like De'Longi! Some other parts (eg Überlaufabschalter) act now not very high but that is not noticeable externally.
