Quote: The one question you want to ask yourself regarding anything which emits a mist of repellent: do I want this stuff on my mirror surfaces or optics?
The ThermaCell has been used by many, with no ill effects on optics; some even place it directly under their tripods; I don't think I would, but that's their choice. I set mine on the floor about 4' from the scope.
