Query: Okay, so the whistle works, but...

... really, what could you expect of a cheap piece of made-in-China plastic? I got two of these for a set of stick-in-the-car emergency kits, and while one seemed fine, the compass on the other didn't know what was up, down east or west. A 50 percent failure rate is not particularly reassuring if I'm planning on using this thing to get out of a messy situation. It is very, very orange, though, so it'll be quite easy for the search crew to find my remains after I get thoroughly lost trying to use this thing to navigate to safety.
