It does the job of heating a small area - nothing more than 4 feet (not the 10' diameter it advertises).  It does not stand up against a 10+mph wind, and that is with a full tank of propane in the base (again, the advertising states it has a tip over protection mechanism - which trust me, it does not).  The material of the entire heater is not strong enough to withstand being blown over - everything was bent beyond working order; the 'umbrella hood,' the pole that holds the heating mechanism on top of the base, the turn valve, and the heater itself - all either bent and ripped from the nuts/bolts holding it together or crimped making it difficult for the pieces to mesh together into a solid piece.  Had the item for less than one season and promptly went into the garbage.
