This fan was just installed and works fine.  It appears sturdy and of good quality, but since we just got it, we can't provide a true assessement of durability and longevity.  We bought this to put in our small gym area of our basement.  I didn't want to cannibalize the limited floor space.  Nothing negative to say about the fan except it seems a bit pricey for a fan, if it lasts a long time, then it's worth it.
