Question: can this be run on batteries if there is no ceiling wire?
Document: Excellent ceiling fan. Easy install and the remote works great. Nice that you can dim the light, a great option if y0u're installing to a one switch existing light fixture.
Great remote fan.it was Easy to install. good price,much cheaper than big box stores.Used in room with 12ft ceiling ,so I had to add an extention rod.Remote only feature works ,and did not have to add wall switch.
PROS- Great aesthetically pleasing fan. Looks like it cost twice as much.- Flush Mount option (best with our 8ft ceiling)- Remote included.- reverse blade option.- Cools nicely.CONS- slighty low hum when on fan speed 2 or 3 ( not too bad)- remote sensor only had two inputs from house(blk/wht) while we also had a red for light.
Westinghouse always builds quality products and this one certainly follows suit to other Westinghouse products I have purchased previously. It's a heavy enough product to make you feel the quality behind the cover, but not so heavy that you can't install yourself. Installation took a little longer than expected (because of remote control module), but if you follow the instructions, you can do it without a problem - they are very well written. Fan is great - love everything about it except one thing.
We've had it for about a month now. Exactly what we wanted. Our Criteria:  1. Minimum, 3 speeds, 2. Reversible, 3. Light,  4. Remote control, 5. QuietIt is working great, everything we had hoped for. We were very surprised to find all our requirements at this price. We have had a better fan, but it was a "Casablanca" and cost $900.
Very nice fan! What I really like is it's very quiet. And looks more expensive than I expected. Great purchase!
This item came with a broken globe but we didn't discover it until the fan was installed. Because it was already installed, I couldn't send it back and Amazon doesn't offer any good solution if just one part is missing or broken. What a hassle. I've been a long time Amazon prime customer but am receiving more broken merchandise like this fan and for the first time, am realizing what a hassle it is when you have to make returns.
This is all integrated into one switch, which then activates the remote control to turn on the fan or light. It would've been nice to be able to turn on at least the light with a switch, if not both. Now it's kind of a pain if someone accidentally hits the wrong switch and then the light and fan both won't turn on. The reversible blades look great, the fan is quiet but has a powerful range, and the dim-able light is a great feature.
These fans are a great product for the price! The look great and keep my room cool! Fairly easy to install
It does what it's supposed to do. I shopped around to compare prices and the price was good and looks nice. Does what it's supposed to do and it's true to the picture.
Answer: yes
