works well for 1 room. I would suggest getting multiple reusable ice packs.not cloolingOur HVAC systems have gone out in our store. We ordered the R.W.FLAME Air Conditioner,Evaporative Air Cooler, 31IN Tower Fan, plus more features. It has been a blessing to us. Helps us to keep cooler than other units we have tried.I live in Texas and really put this product to the test. It’s already 105 here so I turned off my AC and ran this bad boy. I was nice and cool in my living room. I stayed cool in my bedroom all night! The tank is large enough to last about 6 hours on full blast!** if you have an oscillating stand fan you may need to turn it off while running this unit. I found it blows the cool air away from me**I have a small bedroom and this was perfect for the corner across from my bed. I was unable to have a second window air conditioner, because I have only one bedroom window. This solved the problem. Also great if getting a second window air conditioner is too expensive, and an immediate solution is needed.Came in handy during our hot spell. Recommend purchasing to keep rooms cool.I'm in California where we of course have dry heat. It works ok if you keep the ice tank filled up, which is hard because it melts rapidly when it's hot. I used the blue box cubes in addition to ice cubes plus chilled water. The chill is noticeable but not substantial. I will however, give 4 stars to the fans power, as it does blow well on high. Bottom line, wish I could returned this but it's past it's deadline, so I'm stuck with an expensive glorified fan.
