Very useful when the humidity rises to 95%, very easy to use this small 'fridge' that removes moisture, works very efficiently with moderate noise. Portable from room to room even from floor to floor. I noticed that the fan wheel is not centered, causing a vibration of the apparatus; what it will lead over time? A deterioration of the air pulse engine? I call customer service (very friendly) told me that not to worry ... But anyway. A monitor. The warranty is two years!
