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

This whistle was picked because it shipped quickly and it was inexpensive. It works as described and the whistles could be heard and were all functional. It was easy to use.

I needed a gift for my boy's coach and decided to get this. At first I was skeptical but as soon as it arrived, I couldn't help but play with it. The sound is very loud!!! It scared my neighbors. There are 3 different tones to choose from. It's easy to hold but the string is perfect to keep around your neck. I am not sure on the battery life as this was a gift but it's easy to use and seems quite durable. A good choice!

It is SOOOOO loud! I had to put paper in it to muffle the sound a bit. It also only has 3 sound options and I wish there were more.

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.

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!

Love it!! I use it whenever a whistle is required but without the whistle. It works very well.

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.

Worked great until it stopped working 3 practices in. Not sure if its the battery, or the fact that it was cheaper than the other options.
