Question: are the blades wood or metal
Document: I needed a low profile ceiling fan for the master bedroom and the Hunter 20806 fit the bill. Love the brass and dark wood combination.
in my 600 sq. ft. living room I've found this classic Hunter fan to be ideal on a penny pincher's dime. i'm talking 100 degrees max and sitting within 8 feet of the fan, but that's easy in most rooms.
couldn't find a fan I liked in the big box stores. this fan was exactly what I wanted ,and at a better price than evey other one I looked at
Works very smoothly. Looks beautifull. Installation was very easy. Moves air very well in High speed only. Very sluggish and unsatisfactory in Low and Medium Speed, may be because it is too close to Ceiling (6"), or because of the HUNTER Remote control I am using. I am thinking to re-install it with a 3" shim, to keep it at 9" from ceiling.Amazon's Price, Services and Delivery was excellent.
Well, I just installed the new fan and found it to be fairly easy to install. It is running very quietly and looks very nice. Big problem is you can't attach a standard ceiling fan light kit. I found this out when I was almost finished with the installation. The switch for the fan and all the housing for the wiring is tucked inside what they call the "upper switch housing". There isn't any plate at the bottom of this housing to attach a fan kit.
We received the fan and my husband put it up. It is quiet and elegant. We plan on buying another one. Good product.
We had some difficulty getting the outside casing to fit flush to the ceiling (1st try left a 1/4 inch gap) and had to do some bending of the ceiling bracket to make it work...but once we got it up we really liked the look, and it is efficient and very quiet.
Unfortunately I did not do research as to the RPM of the fan. I was disappointed that the highest speed of this fan matched the middle speed of my previous fan. However, it seems to do an adequate job of cooling. (Frankly, I rarely kept my previous fan on at the highest speed anyway as it was almost too fast and it made me a little nervous. But still, it's nice to have that option for the few times you need that extra burst of air.
This fan was of bad quality and finish. I returned this product. The store that I purchased  from was very good to deal with and I would buy from them again.
This ceiling fan is everything I had expected. Quiet, easy addition of a light kit, nicely styled. I am very happy with my choice.
