Works great at recess except I ordered purple and the students are intrigued by the color!

This product was just what I expected. It's a whistle. Nothing more, nothing less. The volume depends on how much breathe you put into it. It can be extremely  loud if you want it to be.

I use the whistle to officiate and the crisp clear sound is what I'm looking for.  You can hear it wven in the wind.

I have  coaches telling me this is one of their top picks in whistles.

Totally loud enough =]
perfect for refereeing soccer games!
