Nexus Safety Whistle

As advertised
I ordered this product for myself and three other elderly neighbors. I have PD and recently had a bad fall and it was some time before I could make myself heard for help. This whistle is easily carried around my neck, and I hope it will be useful in summoning help if needed. It is not cumbersome and can be worn around my neck or affixed to my clothing. Unfortunately two of the women I gave them to are not able to blow hard enough for them to be effective.
