Question: What are the rpms for each of the 4 speeds on this fan?
Document: We ordered 4 of these fans for our house and we LOVE them. they are beautiful and work really well... very quiet, responsive to the remote, and gorgeous. we are thrilled and would def get again.
I ordered 4 Altria fans with 18" downrods spending $3000. One of the downrods was not useable due to a offcenter hole. I wrote to casablanca customer service to ask for a replacement and  received the following response:From: customercare [mailto:customercare@hunterfan.com]Sent: Tuesday, October 30, 2012 8:39 AMSubject: RE: Support email from casablancafanco.com websiteThe PL418 is on back order until the middle of January.
If that flange was not messed up, I would give this fan 5 stars - I'm actually temped to only give it 3 because of that one issue but I do like the fan so far.
Finish, design, and look are excellent. Hands down the best contemporary fan out there, but very dim light. Casablanca would greatly enhance the utility of the Bullet fan by adding twice the light.
5 stars...awesome fan! The look of the fan is very modern and clean. The functionality is great. It also comes with the wall control. Only thing disappointing is it has only one light bulb which is not very bright. Overall great fan!
I had some concerns due to other reviews, but Fan works great, very quiet, even a tasteful remote control!installing takes patience and more time than average, and the blades can scratch easily when they are inserted but still very happy with this product.
If the answer is 'yes' then go ahead and purchase one,if no then there are many other really good reputable fan companies that provide high quality fans. I know because, I've replaced 50% of our Casablanca fans with their competors fans.
This is not an inexpensive fan and new out of the box it was defective. According to the electrician that spent two hours trying to make it work the wiring was faulty. I'm extremely disappointed. Based on the other one-star review this seems to be a bit of a pattern for this manufacturer.
Finally to add insult to injury I received a letter from Hunter Fans telling me if i did not return to them within 15 day parts from original defective fan I would not get a warranty for the replacement fan. Customer Service #421 for these bozo's.
Got two of these a couple of weeks ago and have had not problems with them. Except one problem - the flange that the light unit mounts to was not level with the rest of the fan body. I had to &#34;make&#34; it work by wedging the light attaching base to make that level to the body so the light unit would sit right. Both fans had this problem, one was worse than the other.
Answer: yes
