Title: Very loud, very easy to blow!
Review: I got this to attach to my packs shoulder strap when hiking. It's useful in distress or if you want to try to warn away any bears. I found the high-pitched tone very loud and very easy to distinguish an emergency type call. It was not hard to blow in this at all to get it to make noise. Maybe not as easy as a pea-type whistle, but I think it's louder and better sounding then the pea whistle I have. It's also very lightweight, and doesn't make any annoying sound when walking around with. A very satisfied purchase!
