ok on the burgess propane powered fogger, when the it is first heating mine hissed and spit till it got warmed up. I fogged twice already once the evening i got it than again the next morning. I haven't been able to be out long enough yet to decide if it made a difference or not. they tell you to not breath the fog, but that is almost impossible to do, a respirator might be in order. Basically just wanted to give some kind of update and let you all know I didn't forget about this thread.
