I just wanted to add...two years later...that Rosco is a professional fog machine manufacturer (as well as other theatrical things). The F-100 is a staple theatrical fogger. Although I am not as knowledgeable about fog juice as I wish I was, I can only assume that the Rosco fog juice is of the highest quality in existence. That said, I should comment that the more I research foggers and fog juice, especially the cheapo Party City kind, the more I learn that the pump and heater expect certain qualities to the juice, in particular at what temperature it atomizes at.
