Stainless steel. Look nice. Are high quality. Our electrician commented on how nice of fans we got for our new home. 

We had some rooms we didn’t want the fan to hang so low, so we cut 2 inches off the top and it worked out great! 

There is nothing holding on the top cap thing. So when it was installed it made a noise, our electrician tried to put tape or something so it wasn’t straight metal on metal but had some buffer. It worked! 

Good air movement. Not silent, but since there are different air levels it works out. You can watch a movie on level 1 or 2 and not have to have the sound blaring over.
