Input:
I use these fans in my flower growing area.  The area is screened, exposed to the outside elements.  The fans are at the edge of the screened area in protected sections and they hold up very well.  Some last longer than 5 years in these outdoor conditions and some (one or two) only lasted a year or two.  I order them as I need them and am happy with them.  I could probably get less expensive fans to do the job but these work and give me peace of mind that I will have air movement 24 hours a day, 365 days a year.
