UNIWA Electronic Whistle, Battery Operated Whistle Adjustable 3 Different Loud Whistle Sounds with Lanyard Handheld Electronic Whistles for Referees Volleyball Coaches Teacher, Soccer Sports Whistle

Works good, it’s pretty loud and has different modes. I use it for wrestling practices and everyone in the room here’s it!

Definitely gets the kids attention at practice. It’s easy to use and very loud. I love using this as a coach.

WAY LOUDER THAN EXPECTED! Glad I purchased, hopefully I'll never have to use it.

I really like this whistle. It is very easy to use and comes with batteries. I needed on so that I could ref at my volleyball tournaments. I absolutely love how loud it is. The battery has held up very well and is very light. I also like the shape because it is very easy to hold and the strap makes it very good. One thing I don’t like is the actual tones of the whistle. I feel as the one that best sounds like a real whistle is tone 1. I do recommend this one because I am very pleased with it.

Loud and useful. Use it for down reffing in Vball.

I have had one of these for track before, and it was loud but I can tell you it was not as loud as this one. Great product that serves it's purpose VERY well.

Ok, so this is a very loud whistle! Great out on the playground to get the kids attention!

good and loud😈

Achei que a qualidade do material inferior. Muitas rebarbas. Plástico frágil.

صوت قوي متعدد المستويات

Perfectly fulfills its purpose.

Casi no se oye, no lo recomiendo, ya le cambie 2 veces las marca de las pilas y se sigue oyendo muy poco
