I didn't have high expectations for this. It's small and the cost was low, and I figured, why not try it? Well I'm glad I did. I camped in a tiny little pop up with no AC, and this thing was a life-saver. Once I figured out how to adjust the temperature, it started pouring out cool air. Now, my review might be skewed, because anything that blows air at you when it's 100 and some degrees out would feel good, but I'm a big fan of this tiny contraption, and I plan to use it on all my camping trips!
