Review on 🚨 ust Hear-Me Whistle: Your Ultimate Companion for Safety and Communication by Djkutt Kent

Bought these for a disaster survival kit and love the fact that they are waterproof. Just bite and blow. The whistle will point down a bit, but this is how it works. Loud as hell. They are made out of a type of ABS plastic. Really sturdy and the thickness and connections look like they will last. The included lanyard is good for emergencies, but you'll need a slightly thicker cord if you use it regularly. A great way to announce your location if needed.
