Acme 636 Safety Whistle White

I purchased 2 whistles based on other Amazon reviews and I'm happy I did. I needed whistles for my car safety kits. The whistle is very slim, lightweight and looks well made. Best of all, it's loud! The neck strap that comes with it is also well made. I would definitely purchase this product again.

Loud pitch and delivery was quick

Well made loud whistle. Perfect addition to the key chain.

After reading many whistle reviews, I bought several different whistles to test. This is the loudest small whistle I tested, and the 3rd loudest of all of the whistles I tested. The loudest whistle was the Storm STORM® Safety Whistle and the 2nd loudest whistle was the Windstorm Windstorm Safety Whistle . The Storm & Windstorm required the least hardest blowing effort to get a loud sound, and the Acme 636 only required a moderate blowing effort to achieve a loud sound. Also, the Acme 636 required the least blowing effort of any of the small whistles to be able to get a loud sound. I recommend the Acme 636 Safety Whistle to anyone looking for a SMALL safety whistle. UPDATE: I need to say that over the years my high range hearing has been damaged to the point where it no longer exists. Whistles that I rate poorly MAY be loud to people with full range hearing, but the whistles I rate highly all have a lower frequency which I can easily hear. Something to think about; hunters and other people who have been exposed to very loud noises, like gunshots, may have damaged high range hearing, and may not hear your high pitched whistle. Whereas pretty much everybody can hear a lower pitched / lower frequency whistle. Plus, if I'm injured (think of a fall resulting in broken ribs)I will not be able to give my whistle a hard blow, so for me to rate it highly it must be LOUD without having to blow it hard.

I read reviews that raved about how good this is for an emergency whistle; but it makes a wimpy sound. I can't imagine anyone being rescued using this whistle.
