If you camp, hike or ski then this is a great whistle to use.

Pealess means the cold will not matter and it will blow no matter what the weather.

High pitched and piercing 5 stars

This is an interesting little whistle. There is no ball in it, it is all one piece. It feels different to blow than the old-fashioned kind, but is easy to make a good, loud noise with. It was shipped quickly by the merchant. 5 stars

I am very pleased with the sound and the style of this fine little whistle!
I was also delighted with the set of 2 handy, different sized key rings that were included. 5 stars

The shippging was too expensive it was more then the price of the whistle. Another thing that bug me is that you have to blow very hard to have a loud sound. Not like the other fox 40. 2 stars

I like this whistle's slim design. I wear it when shopping in rough areas. If I am apprehended, I intend to use the whistle to draw attention to me and the assailant. This whistle is much louder than my voice, and carries well across other sounds. 5 stars
