Noopel Emergency Whistles Lifeguard Safety Whistle with Lanyard and Keychain for Outdoor Camping Hiking Boating Backpacking Fishing Kayak Kids Rescue Signaling Loud Survival Whistle

Very loud don’t have to use full lung power just a decent force, hopefully works well for what is needed but just testing it I feel overall solid about the volume DBs, price for two not bad, nice lanyard that comes with clip in a little worried would gives out and maybe whistle fall off but just seems like a clip that isn’t super sturdy and perhaps will give out in time. Very lightweight, small and flat so can fit in pocket easy about two inches long have not tested around water

I have one on my keychain, one on my hiking bag, one on my lifejacket. A whistle is so much more attention-getting than a yell or scream, especially in crowded areas like the swimming area or a parking lot. I carry them for safety. They’ve been holding up nicely after a few months and still look brand new. They look very nice, sleek and well made, and the whistle volume is just what I need.

Very easy to use and lightweight. I keep it on my keychain. It's main purpose is to call my dog in an emergency situation. We've trained her to come back to us when she hears the whistle and so far she obeys it well after a few training sessions. We haven't had to use it in an actual emergency yet, but we've tested it across and entire park and my dog hears it just fine. My wife lets our dog off the leash and i blow the whistle until she arrives to me. She usually bolts straight to me upon hearing it.

This small whistle is very loud! Pros: - Its compact size makes it great for using while hiking, biking, or any outdoor activity. I like the fact that it is made out of aluminum and even comes with a lanyard. - Shipping was fast and had a pleasant experience with the seller. Cons: - On the downside, while the whistle can be ear-splittingly loud, its just that; ear-splittingly loud. The sound reverberates directly into your eardrums because the bevel of the whistle is pointed directly at the user. Overall, I give this whistle (set of whistles, to be precise) 4/5 stars: 4 stars for the quality of the aluminum, small form factor, and very loud whistle sound (since the loud whistle can hurt your ears, I deducted one star). For $8 it is a little overpriced, but you do get two whistles in the package, which is nice.

Really loud and doesn’t take much air/lung power

Handy and loud enough to get attention.

Oh, this whistle works perfect it is nice and loud

This whistle is not for me! It rings my ears when I try to use it. I wanted something I could use to recall my dog but unfortunately the sound of this whistle is too much. I tried covering one hole to give it a different sound and that helps but it’s too much of a hassle to cover the hole before blowing the whistle.

Whistle is loud, when it works. It's not all metal but has some internal parts that are plastic. Those parts can come loose, breaking the whistle. This happened to us after a few days. It also comes with a lanyard that snaps at the slightest tug. Do not rely on this product to work.
