This is a cheap product, but it is sold for cheap, and so you get what you paid for.It was fun while it worked. It does what is advertised.It is basically a piece of flint that is zip tied to your shoe. The directions for how to attach it are on the product package, but they are cropped a bit at the end. If you have basic critical thinking skills, then you can piece together what it is saying.I recommend zip tying it to the MIDDLE of your foot, and applying a ton of the tape foil. They give you a hand full, so don't be too stingy.
