Question: Our electrician broke one if the blades. Can I purchase a replacement?
Document: This fan is the quietest and most energy efficient I have ever seen. It has plastic blades, because they weigh less (reduces unsprung weight, thus they can use a smaller motor and use less power) and are shaped in a way to maximize air movement.The blades feel strong to me, I bet I could break the wood blades on the old fan before these. The LED light is &#34;only&#34; 14 watts but it is BRIGHT and Minka-Aire adds a nice touch of a soft-on (in other words the light turns on to full over 2.5 seconds, so it's not an instant-on floodlight.
I have two of these fans, though one buzzes and the other one wobbles. What's the difference? I bought them at the same time. Pretty look.
It is a cheap plastic fan instead of a metal one what seamed to be described. The price was very high and the picture looked really good so I did not suspect the low quality. It is a pity.
I really like this fan. It replaced an older 60&#34; &#34;regular&#34; fan. This one is much quieter, more air and the light is perfect. I will be ordering another one.
And our ears are thanking us. What's not to like? If silver's not your think, they have distressed Koa as well...My only complaint: the hood for the motor/main fan piece does not fit with the shortest downrod. The instructions actually say to not use the shroud when using the shorter downrod. That's fine, but now we have an exposed black motor on top of the silver blades. Tried to make it work with shorter downroad but couldn't fit it. Nitpick though.
Gorgeous fan. Sleek and the light is very bright. Great quality and easy to assemble. One tip: It is 52 inches but has a lower profile so looks smaller in a large room, it would fit well in a medium sized room.
The light is bright enough to be the only light in our big living room at night - it's that bright.The remote control looks nice and works well. The soft-touch gel controls feel better than the old Harbor eggshaped push button remotes of our last fan.Best feature: It's *quiet*. On high, you cannot hear this much at all. Our wood blade fan was loud enough (and would wiggle and shake the chains) so we'd have to turn the TV up. Now we are finding we're listening to the TV at low volume levels we've never used before.So this fan uses less power, moves more air, has a brighter energy-efficient light, and looks great.
Best everIt is modern looking and very quiet. The lighting is perfect. It was very easy to install. Love the remote control.
