This whistle's patented failsafe design generates the loudest and shrillest, penetrating, sound that can be heard over a mile away. Ideal for personal safety, one blow from this whistle will immediately turn heads and generate attention, especially valuable in times when you can't scream. Carry it in your purse or pocket, around your neck or hanging from the bottom of our pepper spray's key-chain.
Warning: This whistle will not function properly if you have a tube sock, ballgag or apple in your mouth; also it will not function if ether has been inhaled. This whistle is not gauranteed to deter a rapist, and in fact it might arouse him.
