Both are actually pretty genius imo. I've been in my bathtub with an exacto and a pair of pliers 5 times, but I know a couple people who, got busted right after that. It's intimidating to consider you could burn your house down if you panic. I should take some batteries in the woods and practice. The sheriff knocked on my door today. I have a video doorbell and didn't answer it. It was 3 minutes after a pie plate was ran dry on my hot plate and exploded. He looked nervous and was watching behind him. I think he either heard it or someone called it in and he was nearby. It is about as loud as a 0.380, 38, 9mm pistol at least.maybe approaching a .45
