"This is a swamp cooler, not an AC; it adds humidity, it doesn't remove heat."
The '3-in-1 Evaporative Air Cooler' spec means this is a fan that blows air over a wet pad. This process cools the immediate airflow by adding water vapor to it, which is the opposite of what a real air conditioner (which dehumidifies) does.
This product is for someone in an arid, desert climate who understands the limitations of a swamp cooler. It might also serve a user who primarily wants a fan that also adds humidity to a dry room. It is not an alternative to a real air conditioner.
Anyone in a humid or even moderately humid climate should avoid this; it will make the room feel damp and uncomfortable. Users who need to lower the ambient temperature of a room will be disappointed, as this device does not remove heat. A standard window AC unit is a better investment for actual cooling.
