Verified Purchase
It's an excellent evaporative cooler, great for us here in Arizona. The only drawback is that it's rather hard to fill without making a mess. Oh how I wish the fill hole was in the top! Still, it's not a deal breaker, it's a good unit.

Makes patio bearable
Works very well - I live in Phoenix and it makes patio bearable. It should do and an even better job once temperatures are out of the 100 plus. Haven't used the hose connection feature yet - unit will go through the five gallons of water in less than two hours here in Phoenix. It's not air conditioning but it's about all you can do in an open area. If you are trying to cool larger area with more people may opt for an oscillating unit or overhead mist. Product is great for my needs as an individual.

Happy Customer
Very happy with our purchase. It cools off a room quickly, it's not too loud, easily moved around on wheels, and powerful enough to cool two fair-sized rooms when we put it close to the entry between rooms. The water tank lasts a few hours, but is easy enough to refill. It also has a fan-only setting, which is ideal for the mornings, before it warms up. It's great for our dry heat in the desert -- until our monsoons come in, and we'll need to switch to (expensive!) refrigeration. But for now, it's perfect for our cooling needs. We do need to keep a door or window ajar to keep the room from becoming too humid though.
