We blew these whistles in a crowded parking lot after buying and nobody even turned around lol. Wouldn’t be very useful in an emergency that’s for sure, just sounds like you’re blowing through a straw
I have not received the product
I bought these for use as an emergency whistle for jacket pulls of family. They are not very loud and would not buy for the whistle feature. They were made nice and have a nice cord to hang on and make a nice pull with a not intrusive whistle.
