Query: Absolutely love this fan!

Amazing ceiling fan, no motor hum at all, even on highest setting. Clean, sleek, almost blends into the ceiling. I like that it's somewhat contemporary, yet not overly so which could date it in a few years. 3 of these fans in 3 upstairs bedrooms keep not only the bedrooms cool, but the entire upstairs when the doors are left open. One word of caution, fan is extremely heavy so a bar attached to joints must be installed or something to hold this fan firmly. This will also keep the fan from wobbling. I've seen reviews that this fan doesn't sit flush to the ceiling (approximately a 1"-1/2" gap), so my contractor mounted the box higher into the ceiling to compensate for this. The fan now sits flush and looks beautiful!! It's worth it to hire a contractor to achieve the flush look. Hands down the best ceiling fan I've experienced yet.
