I'm glad I test things compulsively before taking them out.

I've had this for only a few months, it has never been used in that time, at some point between receiving it (when it worked perfectly) and now there was a little plastic piece inside that slipped and resulted in this whistle sounding like I was blowing through a straw rather than the piercing scream expected.

It's tiny, it's light, it's loud, but none of that matters if it's not durable.

I bought this because I was worried about the plastic whistles breaking and not being functional when needed. The sad thing is all of those plastic whistles that seem to come strapped to everything as a free bonus still work while this does not.

I was under the impression these were all titanium, they are not, and that plastic piece makes this no better than the cheap ones I have laying around already.

Very disappointed in this product.

Great whistle, but don't rely on it in an emergency

Great whistle, but don't rely on it in an emergency. I had this for several months on my keychain, but when I needed to use it in an actual emergency, I blew and blew and nothing but air went through.

Why? Because the little plastic "plug" that redirects the air and produces the whistling sound, was gone. It was wedged up into the whistle at one point, but now, gone. And my whistle was no louder than the one I produce with my own lips.

I would recommend this ONLY if you're going to keep it in a protective case like an Altoids tin or sunglass hard case, where you can ensure that the parts of the whistle do not drop out, like they did on mine (and on several others, as I'm now reading from the various reviews).

Great idea, horrible design.

it creates a single pitch sound that is not easily distinguished from other noises

Monotone whistle, so even though it may technically be 120 dB, it creates a single pitch sound that is not easily distinguished from other noises. In a noisy emergency, like a storm, or in a situation where there was a lot of vehicle or equipment noise, I doubt seriously that it could be heard..

But as a key-chain whistle it is excellent. It is made of good quality metal, super compact design, adds almost no weight to your key chain, and the workmanship is excellent.

Plan to buy more as gifts.

Buy it! Great whistle.

What an amazing and simple and light defense tool or communication tool. Good for distress. Or just for parents who need a "sign" to get their kids attention. Items works very well, EZ to use, lightweight. Will hurt your ears!! LOL But you don't need to blow on it fully to get sound , with the right "tough" you can get various levels of DB as needed. Light is nice free thing included. I recommend this whistle for anyone, but especially kids and women.

A beauty.

This whistle is extremely small! Great for keychains. Bombproof. I'm not sure about the 120 decibel claim. I will say that when trying it out, my kids and I were outside. For me, the sound was loud but not ear piercing like some whistles, aka the Storm. My kids held their hands over their ears because they thought it was quite loud. Maybe it projects well instead of blowing out the users eardrums.

This whistle doesn't disappoint!

Excellent whistle. Very small but loud. Easily fits on key ring with the small led flashlight which by the way activates if dropped in water. The flashlight also has a manual button. I bought two and gave one to my girlfriend as a safety whistle. She loves it. It's a great gift for any occasion.

Whistle is loud and clear like the claim. The light is bright and was an added bonus.

love the small size and weight of this whistle. i am disappoint of this free flash light. it's good overall with a fatal design flaw. one can accidentally pressed the on and off button if stored in a bag rendering a spent battery when you need it. i gave it a five stars anyway as i am buying the whistle after all.

Loud. Small. Cool.

Very small and very light weight. Only four stars because of cost, but I carry it everyday invisibly on my keychain and therefore I have a very loud attention getting whistle when I need on. I would prefer one a little lower pitched buy this gets the job done.
