KTRIO Whistle, Metal Sports Whistles with Lanyard, Loud Crisp Sound Whistles for Coaches, Referees, Teachers, Training

Used for calling my dog out of the field. Good sound, nice and loud. The size is perfect and it is of good quality. I like it and so does my dog! Beets yelling any day. I have used it when alone for safety measures also. You can't go wrong with this purchase.

I monitor recess time at elementary school and needed a whistle to corral the kiddo's. High quality. Great value and works great. Kiddo's have no issues hearing the whistle from one side of the playground to the other. Comes three to a pack to share with friends or incase the one you are using is misplaced.

I got talked into coaching 3rd and 4th grade boys basketball and I needed a cheap whistle. These work great! They are a little cheaply made but for the price they are great!

works well for solicitors they don't call back quality is very good sound is just right size is perfect to carry in your purse

great ear-piercing sound, great to blast into telemarketers' ears... got to use it about 15 mins after I opened the box... happy camper

Husband used it all football season, works great!!! Perfect all around !

Received the three whistles very quickly. They’re shipped with a lanyard and , for the price, you can’t complain. It’s not a heavy duty whistle but it does the trick.

Great product
