As a sound engineer and a dj, i am good at estimating how loud different sounds can get. This whistle gets their attention really fast and gets them to quiet down in a timely matter.

Best whistle available, great for lifeguarding refereeing and rescue. Strong and durable. Fairly effective. Great for lifeguard refs.

The whistle takes a disappointingly large amount of air to blow loudly (or to even get it to make a whistling noise) that means, the one who'll hear it loudest is you. Also makes it difficult for others to tell who you're whistling at.

The whistle i recieved is either fake or defective. If this is the original, than it is a pretty cheaply made product, with what looks like plastic from the mold inside. Secondly, this item is not eligible for return.

Utterly unimpressive marketing hype. No returns. Very dissatisfied.
