I know folks that spend a lot of money on their preps, and let's face it, it costs for quality equipment and survival goods. But sometimes a new gadget comes out, looks cool and seems useful. I suggest you do two things before buying. Wait until someone offers reviews, don't be the first person disappointed by a new product. Most importantly, have purpose in your purchase, know why you are buying it and how to use it.
Let's say there's a new Fire Starter that comes out for $29.95 + shipping. It promises to deliver a flame under any conditions and so on. It's purpose is to start a fire, plain and simple. If you are like me, I have multiple ways and devices for starting a fire. From matches to magnifying glass and even the good ole dollar BIC. Push come to shove, I can use the natural material around my house to do what I need to do. I would put that money toward another tank of propane.
Don't get me wrong, if that Fire Starter can start an instant fire under water, last for 1 million uses, and is smaller than a dime, I'm buying it and giving everything else away. Just know why before you buy.
