Review on Vicks Starry Night Cool Mist Humidifier for Medium to Large Rooms - 1 Gallon Tank, Baby and Kids Rooms, Light Up Star Night Light Display, Works with Vicks VapoPads by Heather Davis

We followed all the instructions, filled the tank, soaked the filter and turned on the fan. There was no indication of moisture escaping or even where it was supposed to be coming from. We put a paper towel where the only fan outlet was and left it on for two hours and the paper towel wasn't even wet. He brought the mirror to the exit and not a drop of mist. I even have a digital and analog humidity sensor for my greenhouse, which didn't register any increase in humidity in the small sealed cabinet. I think "invisible fog" is a tricky way to say "no fog". However, it sheds a lot of moisture on whatever surface it is placed on. For example, the entire tank dripped onto my clothes in the closet and the wooden floor after leaving it with the sensors overnight.
