Review on JULBEAR 6PCS Safety Survival Whistles - Adjustable Reflective Lanyard - Emergency Plastic Whistle for Boating and Marine Safety by Flex Graham

>. These are inexpensive, loud, durable whistles that are lightweight and highly visible. I bought these for my grandkids to wear on camping trips. Lose yourself, calm down on 5 and 7, whistle help is coming. But if you are completely lost, the screaming and crying will kill the noise of the children. Not a whistle. Works as long as there is breath. Teaching a child how to use it is also not a problem.>. The lanyard is bright orange and braided with reflective material, easy to see day or night, even part of it. DOES NOT GLOW IN THE DARK but reflects light falling on it.>. The whistle has a distinct sound, it sounds like a whistle but not the usual one. Young children can overuse them for fun, but the role of the parent is to teach them proper use, not just play.>. They can be used in a large or busy park, campground, fairground, etc. Where separation from a parent is possible, these whistles can save lives and much anxiety.
