Review on 🔊 The Original Worlds Loudest Whistle: HyperWhistle - Up to 142db Loud, Long Range, for Referee, Coaches, Instructors, Sports, Teachers, Life Guard, Self Defense, Survival, Emergency uses by Matthew Perez

I haven't had the courage to blast that thing at full volume yet. Even with free earplugs. I find this product is best used with a can of compressed air as an early warning device in a Home Alone or New York Alone situation. It is very loud. 3 different sounds to stun you. It's in my wild animal bag; just in case I need rescue from the MOON. The moon is considered a desert, right? I bet NASA could blow this thing up if I was in Home Alone 7: That Movie on the Moon!
