HyperWhistle (Safety Orange

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

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

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.

Wolf whistle

Nehme das Ding regelmäßig als Zugbegleiter vor der Abfahrt am Bahnsteig. Man wird definitiv gehört. Absolut erstklassiges Pfeifchen.

This is really something one of its own. Generally, people wouldn't need this. I bought out of curiosity as well as in some hope of using it in the future - which actually seems not happening.

+++ TRES BIEN +++

This whistle is not your average sports whistle; it is super loud and has a range of up to 2+ miles, an impressive eight times the range of an ordinary whistle. One of the standout features of the HyperWhistle is its incredible sound output. A sound pressure level (SPL) of up to 142dB is eight times louder than your typical whistle. This makes it perfect for various situations, whether boating, attending sporting events, ensuring life safety, camping, hiking, or even police use. The durability of this whistle is also worth noting. It is built to withstand all weather conditions, making it a reliable companion no matter the environment. Whether it's raining, snowing, or even underwater, the HyperWhistle will continue to function flawlessly. I also appreciate the attention to detail in the design of this whistle. Its unique radial tri-frequency design ensures that the sound is carried efficiently and effectively, allowing it to be heard from a distance. Additionally, the whistle is naturally buoyant, adding an extra layer of convenience for water-related activities. The HyperWhistle comes with reusable hearing protectors, which is a thoughtful addition. This ensures that you can protect your ears while still enjoying the powerful sound of the whistle. The easy clip-neck lanyard is also a handy feature, allowing you to keep the whistle within reach at all times. It's worth mentioning that the HyperWhistle is a patented design (US8925478), which speaks to its uniqueness and quality.

There’s a reason the whistle comes with included ear plugs. You can seriously damage your hearing with this whistle which makes it more difficult to use. Super loud and you get what you pay for. Whistle is durable, well made. Color is as described. Lightweight, yet it’s bulky. Obviously it’s water resistant you can blow it under the water it states. My only complaints is the bulkiness you can’t just casually wear the whistle around your neck for EDC unfortunately.
