Product review (5 stars): I would buy it again.
I don't usually write reviews, but this little fan is GREAT!  It starts spinning at lower temperatures than its big brother (Caframo which I bought at the same time).  If the stove gets very hot, it has a little tab on the bottom which lifts the base slightly so the fan doesn't overheat.  It is also quiet enough that I can sleep in the same room.
