ZHT Electronic Whistles for Referees with USB Charging, 3 Tone High Volume Emergency Whistle for Referee Coaches Teacher, Outdoor Camping Hiking Boating Safety Whistles with Lanyard

This whistle is extremely useful! The battery lasts a long time, and the sound is loud, clear, and effective. It’s very easy to use and works perfectly without effort. What I love most is that I don’t have to put it in my mouth like a regular whistle — this is perfect for me since I work long hours, and it’s much healthier and more convenient. Absolutely love this product — 5 out of 5!

“Electric whistle for coaches in black. Compact, lightweight, and with a powerful, clear sound. Perfect for grabbing attention during any training. Highly recommended!”

Can't blow a whistle with a mask on. I guess you could, but it would be uncomfortable and inconvenient. This electronic whistle is rechargeable, which makes it much better than one with replaceable batteries (my opinion, obviously). It's loud enough to be effective, but maybe a tad bit less than my Fox40 at full blast. The other thing I like, something I didn't anticipate, is that it's actually faster to call infractions. So you have to be careful not to step on a game too quickly in case, for example, there's advantage and a call would unnecessarily disrupt a game. Not having to constantly bring a whistle to my mouth actually feels really good so I may keep using this as the masks slowly disappear and rules relax (fingers crossed). Quality is more than acceptable. This model also has three selectable trills and varying loudness settings, so it has some options you can play with. The light is cute but almost useless. Anyway, as electronic whistles go, this model seems to have the best mix of features. Plus, it's rechargeable and a charge lasts me many weekends. It hasn't failed me so far (I've used it off and on for 4 months). If you need one this model is worthy of your consideration.

I ref U9 - u19 soccer and this is very good and loud. Not sure what the light would be used for but the various tones are nice to be different from nearby fields and easy to use. I like that it is easy to recharge the battery and I have those spares for some of my flashlights Edit- 4/25/21, this is a great whistle, I have done about ten games so far and it is very loud. Taking off one star due to yesterday I did a game in light rain and after half time it stopped working. The description does clearly state it is not waterproof. But since this is supposed to be used out doors and soccer is played in the rain, I hoped it would at least be light rain proof. It makes a barely audible squeak now. Light comes on, battery charges to 4.2 volts, on a 3.7 volt battery. It is just the speaker does not make a sound. Not sure if I got water in the speaker hole, or through one of the buttons, or where. I was wearing a rain jacket so it was mostly covered by the sleeve and only light rain for about 25 minutes. Reminds me to always carry a backup whistle just in case. But harder to use a real whistle and wear a mask as required by facility.

get asked about this item all the time. Before I started using it, most people had never even seen one. This whistle is the best - it is loud, I can change the sounds and volume, and I never have to worry about cleaning it since it is button-operated. The kids I coach always want to try it, and it’s a great icebreaker with the younger ones. Everyone wants to hold it!

Very loud and distinct

To say the least this product is amazing. The quality and durability of this product is really great and strong. The whistle comes with three different tones. And three different volume settings. The whistle also comes with a flashlight. While I have been using this product for a couple of months now I can’t say it is great. It has a great sound quality which is very loud. And like I said the durability is great highly recommend for use At the time of writing the first review which is above. I did love the product so much that I purchased a second one. well unfortunately it did have some tech. Difficulty. the sound on it was supper low and not loud. Well I contacted the support team and they where vary amazing in there efforts to help me and they where able get my problem solved in 2 days. I do not want this to be a bad reflection of the product but in return a positive on. Thank you so much to the Slongera team for the amazing support.

Lasted less than 2 months. It was great while it worked.

ホイッスル機能としては良い

Lo utilizo para clases de Educación Física, dura mucho la carga, esta super!!! A un año de haberlo comprado no la e cargado todavía, dura muchísimo la batería y la uso 4 veces a la semana

Muy buena compra, recomendable, buena calidad y buen sonido.

Could have volume control

The product is of very poor quality and cannot be used after just one charge. The tone and sound changed immediately after use. I would like to request a return. However, after the purchase, I shifted from Kozhikode to Hyderabad, where return service is not available. Kindly arrange a replacement with a better product here.
