Camera a little big and a little bit noisy but this is not a concern because it is not used in a living room. Our bathroom had a very big problem of moisture, the walls remained wet throughout the day and the ceiling was moldy and droplets. We are therefore impossible to install a flat aerator. After the first two hours of use, the ceiling and the wall of the bathroom was finally dry. With the thermostat, one can choose the humidity in the air from 80% to 30%. In France, it is recommended a rate between 40% and 60%. We have therefore chosen to put the thermostat 4 or 5 is between 60 and 50% humidity. The device starts to work according to the ambient air of not forgetting problem when children are taking a shower;)
