Very satisfied with the device. Yes, it does not moisturize as quickly as ultrasonic, but it is devoid of all its other disadvantages (there was an experience with three humidifiers). No more dry nose in the morning. HOW TO REMOVE THE CLICK: I put WD into the base of the fan legs, just a few drops - after that the clicks disappear for a long time. It takes acomuple of minutes on the strength, and is not difficult. A detailed review (mine) with photos and videos can be viewed here:
