Excellent air conditioner for the price. However, this is definitely for small rooms. I have a small bedroom that this works perfectly for, getting it nice and cool aircon is dripping water within an hour on the highest setting. I then turn it to setting five on low incredible, and it keeps me comfortable all night. I also bought one of these for my slightly larger studio room, and it takes quite a bit longer to cool, so be aware of your room dimensions in regards to the BTU rating. As well, just a quick tip I've learned. If you leave this off and it rains, then turn it on; it WILL be noisy for a while.
