Title: Deafness enhancer
Review: I bought a couple of these whistles, and must say I am disappointed. The shape of the whistle, this may not be clear in the photo but it is J shaped, seems to point the sound right back towards the whistle-users ears. I was almost stunned when I gave the whistle a big blast. Yes, the whistle doesn't cost much, and in this case you get what you pay for.
