UNIWA Electronic Whistle with USB Charging, 3 Tone & 3 High Volume Hand Emergency Whistle for Referee Coaches Teacher, Outdoor Sport Game Camping Safety Electric Whistle with Lanyard

Nice and LOUD whistle! I bought to referee volleyball games at our church. It's easy to use and adjust sounds and pitches. Great buy for the money.

This whistle is loud. It works great for recess duty.

I use this for my Cross Country team. It's super loud and saves me spitting all over a classic whistle. It has 3 sound settings and 3 volumes. It has a small flashlight, which I don't find use for but is a nice addition. I've had a different digital whistle that had a unique charge port. This one uses USB-C which I have everywhere, making this so much more convenient to charge. I've dropped it a few times and you can't even tell. This is SO convenient for things like intervals and sprints. I'll be using it for the foreseeable future.

Other than that, does its job.

I have tried at least 5 different electronic whistles over the last year or so and found one that I liked... BUT then I got this whistle and it is my new favorite. Note I bought this whistle and this is not part of any promotion. It sounds the loudest to me It can be Left ON It is somewhat annoying :) I keep an electronic at our Back Door to call my pups in when they are not right at the door. The majority of whistles I have tried require you to turn them on then press the whistle switch. This one has an On/Off switch and stays on for weeks when left on a shelf so all I have to do is grab it and press the whistle switch. Now I understand that some folks may be carrying their whistle in a pocket or running around with it and one that goes OFF after a bit may be better for them, for me a Dedicated ON switch is a must. The sound seems to be the loudest of all the whistles I have tried and the sound I have selected has just a slightly annoying sound to it and it really gets my Pups attention, which is what it is all about for me. I also love that it is rechargeable, I am so over buying and throwing away AA and AAA batteries...

Love this whistle. I have an electronic Fox40 whistle, but it didn’t last long. Waiting to see how long does this whistle last me. So far, more features and louder than electronic Fox40.

Good product and $, fast shipping. It;s really noisy

It sounds like a smoke alarm. Extremely loud regardless of the volume dial. Waited too long to return so I'm stuck with it.

So far so good. Charged quickly and works great. It's LOUD!

Excelente producto. Calidad y precio.

Muito bom.

Very convenient product. !!!

The only positive thing I can say about the UNIWA electronic whistle is that it's loud. As other reviewers have noted, it does NOT sound like a whistle -- it sounds like a smoke alarm. I accidentally dropped it onto my carpeted floor, from a distance of less than a meter, which caused the battery cover to pop off and the battery to fall out. It was a struggle to get the battery back into place. Be forewarned that the rechargeable battery is NOT a relatively easy to replace 18650 Li-Ion cell. Put simply, the built quality of the UNIWA electronic whistle is mediocre, if not poor. I cannot recommend this item.
