HyperWhistle The Original Worlds Loudest Whistle up to 142db Loud, Very Long Range, for Referee, Coaches, Instructors, Sports, Teachers, Life Guard, Self Defense, Survival, Emergency uses

I was curious as to how loud a whistle could be do I bought one of these… damn me, it’s incredibly loud! I didn’t blow it very hard first time and it still made my ears ring. You really need to wear ear plugs if you’re going to blow it hard, because it’s way louder than you’d think possible.For a whistle, it’s very expensive, but it’s really well built, very lightweight and its power is undeniable - it is easily the loudest whistle I’ve ever encountered, by a long long way.I’ve got it for emergency use, and it’s said to be audible 2 miles away, so it’s functional and very handy if you want to be heard!Don’t blow it in a small space tho - you’ll know about it if you do!!!Awesome emergency whistle, two thumbs up 👍🏻👍🏻

It does exactly what it says on the tin, it is very loud.

Ear busting

Works as described and loud. Very loud. Wear the protection

Yeah i think this will be a good item to carry around for safety, if i get unwanted attention , i ll be blowing this bad boy, with all my might, worth the money if it saves your life

It looked a great product but it said it was delivered no information on on where it was left but when I returned home nothing was there, neither listed through my letter box or in either of my bins or down the side.

Extremely loud whistle, a little expensive for a bit of plastic, but it does the job.

Great product rapid delivery many thanks
