Just wanted to give you a quick update. I received the 3 solar fans a couple of days ago and installed them myself. First of all, they are obviously state-of-the-art and extremely well made. I'm also impressed at how much air the pull out of the house even with minimal daylight---cloud cover, early/late in the day---as long as it's daylight they work! The house is now staying very comfortable even on the hottest days here in Hawaii.
Great product---thank you!
