Very loud - my ears are ringing after blowing it, and I like the pain
Floats - obviously good for in a pool
Looks like a vape pen - a patron asked me to not vape around her children, I replied by blowing the whistle at a running child
No good way to hold it - it is quite difficult to have a firm grasp and still be able to have all the sound come out
Mouthpiece - it's difficult to get a good seal on the whistle and still blow through it hard, I also have to clamp down on it with my teeth which isn't comfortable
The full sound is directed to the side - most times the whistle is louder to the side
All in all it is a very loud whistle, even louder than the air horns we often use. But, for my application it's not suitable for everyday use. It would however, be perfect for an emergency whistle.
