The unit has been working almost 14 days well. Silk tonight but come no more water mist, only the warming plate still becomes hot. The humidifier originally was very good. A 20sqm room could be within 2 h of 35% rel. Bring humidity to 55 to 60% humidity. The still very bright light was disturbing in the bedroom. Fan noise and the bubbling in the water tank is used to, but you can sleep with it. If the replacement device works persevering I would forgive 4 stars. Because of the failure after such a short time but only the minimum rating. Addendum: within 2 days the replacement unit was there. Now we have a pleasant climate again.
Pro: highly efficient, acceptable quiet, large tank. Negatives: no humidity sensor, no time schedule, no bedrooms feature for the operating light.
