Overall the fan works well for our 12x15 room,  pushes down adequate amount of air and at highest speed should be good for even bigger rooms too. I just took away 1 star as one of the crystal piece was broken on the inner ring on the light. At high speed the crystals tend to vibrate & make noise that can be bit irritating. I am fine with low or medium speeds and that tends to keep crystal vibration to a low or bearable level.
