This is a very attractive modern looking fan that really moves the air.  We placed it in our living room and it looks great and works great. We had to have someone come and install it for us as it was different than other fans that we have installed ourselves. It has no pull strings, speed is controlled on the switch installed in the light switch on the wall.We moved this fan to the bedroom and it makes a constant noise that is so loud that we can't sleep. We have had it checked by our handyman and he states there is nothing he can do. We are going to have it replaced.
