I wouldn't use it. I don't have anything big enough to make me worry about making it let go before it decides to. Like Steve said, part of the draw of garters is that they're so friendly. I want mine to come out and want to approach me.

I actually saw a video addressing the listerine thing earlier today. The guy in the video basically said that if you knew what you were doing you didn't need listerine to get a snake off your hand lol.
