I admit that I like good-looking little gadgets, which is at least partly why I bought this. It's cooler looking than a typical whistle, but it's also functionally great. It is compact, virtually weightless, rustproof and very loud. I tie it on my backpack strap so that if I were to fall and get hurt with my pack on I could reach it easily.
