Yep, I used Mr Hearter last year too on FDD, First Day of Deer. I have one of those outhouse popup blinds and when I got too cold and wanted to go back, that is when I turned on the heater and warmed up. It helped me stay in he woods longer. Unforunately, the only deer I saw were 2 does running at me. They almost ran into the blind but kept on going. I didn' t get one during that hunt but will bring it again with me this year, same place. The does were spooked I believe from another hunter, not me. The heater does have a slight sound and odor and I only use it to extend my stay.
