This little evaporative cooler is amazing. It cools air between 6¬∞and 9¬∞ in my bedroom. It makes a difference having moist cool air blow over me at night. It is easy to set up and use. And the controls are fairly intuitive. I do wish that it had a larger water reservoir. Even topping the tank off I sometimes don‚Äôt make it through the night. But, it blows the cooler morning temperature air as a fan.
