Its hard to find the words describing the enthusiasm and pleasure I have already experienced since installing this fan. I am pleased both with the fan’s performance, and its absence from the well packed box in which arrived several months ago and in the interim has been assuming substantial space in my bedroom closet.  The fan has four settings numbered one through four. Four being the fastest.   As it accelerates to level four, the curtains begin to blow with the high velocity air movement.  It is pleasing to the eye and functions as desired.
