I had the opportunity to try out this new ceiling fan over 4 days of boondocking at King's Canyon & Sequoia National Park this last weekend. It did a decent job bringing in cool evening air and was VERY quiet (...kept it running at night).
It doesn't bring in high volume of air (like a Heng's or MaxxAir), but you can feel it while laying down and it is very quiet which was my goal (...also just ~.25amps so very little battery use).
I will be adding another to one of my other RVs that has the pull handle open/close mechanism instead of the crank as it is a particularly good option for that situation.
Keep cool all!
