If it weren’t for the fact that it would be more of a hassle to return this than the $4 I spent on it, I would.
The flint (The main thing I bought it for was painted on, so after a few strikes, it was worthless. Also it fell apart on the 5th strike.
Both the thermometer and the hydrometer seem to be off, and the whistle is a joke.
Yes, there is an LED light but apparently there is no way to change the battery, so when it dies, so does the light.
Remaining is a functional (plastic) magnifying glass suitable for examining splinters perhaps, and a small mirror that you can use to signal for help once you realize you ventured into the woods thinking this thing would help you survive and now you’re screwed.
In short, don’t buy it.
