FB850 solar fan with temperature switch July 18, 2011
Reviewer: Arnulfo Hinojosa from Waynesville, OH United States  
Tracking the (2) units was easy and delivered as promised.  Overall product quality is high and installation was simple. Expect many years of serivce and only time will tell if the return on investment savings materialize.
