Document: quiet beautiful fan , had to buy two more for other rooms
I love this fan. It moves the air very well, you cannot hear it at all when it is on the lowest speed.
There were many flaws in the finish and that was very unexpected from this company. I'm still debating whether or not to just return the fan. It seems the quality of anything has gone downhill.
Hubby hung the fan in about an hour on a lazy saturday afternoon. No wobble whatsoever, and the motor is almost silent. Nothing about the fan feels cheap, and had plenty of hardware for putting it all together (no plastic screws!)
I found that a drill with a longer correct screwdriver attachment worked better than trying to use a hand held screwdriver. If your drill attachment is magnetized that's even better to keep the screen from falling to the floor. All in all, the fan wasn't hard to install by myself, and it works perfectly when I turn it on. It's quiet and the fan appears balanced at all speeds without using any of the enclosed balancing pieces.
This fan is absolutely beautiful. I had to replace an old ceiling fan on a high ceiling, and after purchasing the additional 12&#34; extension it fit perfectly into the supplied holder. The new fans have a special holder that attach to the wiring box, that allows the fan to hang straight down regardless of the pitch of your ceiling. The holder makes it easier to wire the fan as the fan hangs in the holder instead of trying to wire while still holding onto the heavy fan motor.
we bought two of these fans. we love them so far. very quiet! was skeptical buying them without seeing them in person. glad i did.
We put this in our daughters bedroom. It matches her white furniture and the quality and value are excellent. Very quiet motor and it moves the air perfectly. We highly recommend this one.
PRO: Quiet, easy to install, great styleCON: must use halogen lamp (100W supplied) with &#34;special mini-can base. prohiits using energy efficient compact fluorescent or LED replacement lamp.
I chose this rating because I am finally cool at night. I would recommend this item to anyone. Thank you
