We have two other faucet humidifiers with cool mist. One is a cow and the other is a standard teardrop shape. This frog is the worst of the three. There is a pole that goes across the top of the tank and aligns directly with the hole where the mist comes out. So I can't see the fog coming out very well and I can never tell if the level is right. As the mist rises straight up, it settles on the humidifier itself and all surfaces around it, leaving a white film. I know this is partly due to the water I use, but we don't have this issue with our other two humidifiers.
