Three Tone Electronic Whistle - Handheld 3 Distinct High Volume Loudest Electric Whistle with Lanyard for Referee Coaches, P.E. Teacher, Marine, Police,Outdoor Camping, Self Defense Emergency

Must buy ... it's a good product.

Small but works great, really loud

The Xflyee Electronic Whistle is exceptional! With three different tones and high volume, it stands out as one of the loudest electronic whistles available. The sound is clear and effective, making it perfect for sports, emergencies, or outdoor activities. The handheld design is comfortable to use, and the whistle's durability is impressive. It’s a reliable tool for getting attention or signaling from a distance. Highly recommended for anyone needing a powerful and versatile whistle!

I bought this product thinking it would be a good alternative for my sick mother-in-law to call us to her bedroom when she needed our help, since her voice is very fragile. The whistle is incredibly loud, crisp and clear. It does have a far carrying sound, which makes it excellent for outside sporty usage. But for indoors use, it is too loud and uncomfortable for the user. It is painfully loud indoors and creates that ringing noise that deafens one for a few minutes. It is also a little more bulky than I imagined, making it unwieldy. But it is a good, durable, product that does what is promissed, only too well. It just isn't appropriate for use inside small enclosed spaces, especially by small fragile elderly people.

It’s a little big but not sure if they come smaller. It’s very loud and lightweight. Gets the job done.

this whistle is incredibly loud and wouldn’t be incredibly effective. If any taxis would come close to my hotel lol highly recommend this whistle.
