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 am a volleyball ref and when another team refs the match with me they sometimes forget their whistle!Having an automatic one has been great because I don’t have to buy an abundance of regular whistles.It’s loud with three different settings. It comes with a velvet bag to carry it in to help keep it safe!Great product, quick delivery, small and light enough to fit in my ref bag.It’s built nice so it doesn’t feel like it’s going to break easily. Battery life is great.You will not be disappointed in this product!

Very good whistle. It works like it should.

First, I bought this as a gift for an elementary teacher. She had seen another teacher use a different electronic whistle.Her comparison was that this one was louder, had more bells and whistles ( different types of chirps) and was anxious to see how long the batteries would last. She is glad that they are replaceable. She was able to use this whistle to recall her students during recess from the playground to form a line to enter the building and return to the classroom. It saves her voice and is more "professional" if parents are visiting so she won't be accused of yelling at her students. SMH...One of many things teachers have to worry about.

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.

Love these little guys. I’m a 5th grade teacher and use them to get my kids attention during recess and sometimes in class. It’s super loud, light weight, and has a great battery life.

Works well! As a sub, I reluctant to use another person’s whistle, or any whistle. This is great as it works on the touch of a button and can be borrowed without fear of directly spreading germs.

Bought for my daughter and her volleyball team, this is very loud and battery last a long time. very durable.

Whistle is generally loud when the gym is not filled with multiple classes. But when there are multiples classes the whistle is not loud enough and students can not hear the whistle. I’m a bit disappointed but it still works when teaching one class
