I bought the AF-600 misting fan is the middle of the summer, desperate for some relief on our back porch from our hot and humid Gulf Coast summers. I originally was attracted to the misting feature, but was most impressed by the strong fan power. The fan is strong enough to blow away the marsh mosquitos, which makes our back porch more usable throughout the year. I've had it for about 10 months now on our covered back porch and it has held up extremely well being just semi-protected from the elements. Highly recommended.
