Red Emergency Whistles with Lanyard & Mouth Grip, Loud Crisp Sound, Plastic Whistle Ideal for Lifeguard, Self-Defense and Emergency

Nice and loud. The rubber tips really help you hold the whistle.

Low cost. Good and noisy. The mouthpiece cover works well for extra thickness and a compression surface when you are holding it with your teeth instead of your hand.

These whistles are very loud! You will not have any problem with people being able to hear you!

It has a good whistle but the ball in it is very odd.

Good inexpensive whistle

I bought these as a noise deterrent. While on an early morning walk with my 2 small dogs, a coyote stalked us. Shouting didn't work. I was concerned an air horn would be impractical so I chose these whistles. They are lightweight and very loud.

A safety whistle that’s not safe. Not sure how to square the circle on this product. So, what’s the problem? Well, the nylon lanyard is securely crimped and attached to the whistle’s eyelet. There’s no breakaway feature to the whistle meaning that if it got hooked or snagged on something, you wouldn’t be able to blow for help because it would be efficiently strangling you with its unbreakable nylon cord.Actually, once I started researching it, many survival or recreational whistle lanyards do not feature a breakaway design. I wouldn’t recommend hanging this around your neck, and instead suggest it be attached to a belt loop, wrist (like the NFL refs do) or backpack zipper. Since it’s a widespread trade design, I can’t really knock this product for that element, but I can offer that general safety caution.As far as sound, it produces a piercing, really high-pitched tone. We blew ours on a high school football field, and it was easily heard at the other end. It’s a little tinny, but it works. The tone doesn’t "hang," though, so repeated blowing was required to sustain the sound. I liked the soft-plastic mouth guard that provided extra traction for blowing. One other note, natural cork will dry out over time negatively impacting the whistle’s performance. Or repeated blowing will coat it with saliva making it mute. Go for a pea-less model.Neither toy nor tool. Three stars.

The whistle is very loud, which I expected and needed. But a really good feature is the silicone band that allows me to comfortably grip the whistle with my teeth, which I frequently do.
