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

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.

It’s loud and easy to use

I use this on the playground at school. It is very loud! I wish it had more of a whistle sound as it is more like a basketball buzzer sound.

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.

Works great!

nice volume, has great sound selection (it was a gift)

Teacher here on recess duty- works wonders and has great volume. I always try to hold it at arms length because it really is loud.

I got two of these for cross country practice for myself and the assistant coach. I have to say, I wasn't expecting it to be that loud, but it DEFINITELY gets everyone's attention. Using it indoors will really leave a little ringing in your ears. I started pointing the end of it to my leg to help reduce the sound indoors. Outdoors, the sound carries a pretty good distance. Having three different whistle sounds was a good idea, but at the volume level it's hard to discern any difference when you are holding it.

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
