Review: I'm a referee and this electronic whistle enabled me to effectively call games earlier this year - 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.

### ⭐⭐⭐⭐⭐ Loud, fun, and easy to ese
*by E***. on August 23, 2025*

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!
