We’ve had this fan over a year now on our front porch.  It’s exposed to humidity, high temperatures, and lots of dust.  The fan is easy to clean and still looks just as good as install day.  The blades are holding their shape well so far.  Humidity in south Florida can easily make them sag.  It’s height is perfect for lower ceilings, other models wouldn’t have provided enough clearance for tall folks to walk underneath.
