Question: Can you add a light fixture?
Document: The fans are working great on my patio with the light attachment on it too. Keeps us cool and the patio lite!
Wwhile the fan looks ok, and puts out a fair amount of air;  the fan stopped working after a month. Very disappointed !!!! Don't buy it. It's a waste of hard earned money
We bought two of these for our porch. They are lovely, lower the temperature of our patio and keep mosquitos away.
To me this shows the manufacturer has taken the time to make sure every blade and blade holder is perfect. Only time will tell on how reliable it is but so far it's two thumbs up.
This is appears to be a decent product and most importantly, was easy to install. The pull chain is relatively short.
These were easy to install even for those who are not too familiar with electrical. Went together easily and up quickly! They look great and work very very well. Perfect for the screen porch we have them in (bought 2) to replace the warped indoor fans that were previously installed.
The plastic blades look a bit cheesy as they are plastic. But this is for outdoor use. Neighbors installed an indoor fan on their patio a couple of years ago, and the wooden blades droop quite a bit.
The fan does not provide a lot of down force air flow. The plastic fan blades look plastic!
Put this in my screened in porch after the non outdoor fans blades drooped. It is very quiet and attractive.
Purchased Outdoor Ceiling Fans for underneath our back pation cover. Fans were shipped promptly, look and work great. Very pleased with this purchase. Thanks
