The Vicks cool mist humidifier is great to have around. Winters can get dry with all the heating we use, so when things are too dry or our kids have croup cough, we put the humidifier on for several nights. It does what its supposed to do by adding moisture to the room. The canister is easy enough to fill. Just twist the bottom off (that can be a little tough at times), then put it under the tub faucet. When its full you snap it into the base, which fills the bottom up with water. The dial allows you to choose the level of humidity that you want. Above are the pros. Here are my issues with the humidifier: I have active kids. On several occasions they have knocked into it and spilled quite a bit of water from the base onto my carpet. Also, the inside is kind of impossible to clean, so even though it gets dusty in there, there's really no way to wash it off. That dusty area is the spot that is misting up your room. If you are sensitive to dust or mustiness then you would not be pleased.
