New flash: it honestly does make a difference from whom you buy your self defense weapons from. For example, brand names make a difference when buying some items like shoes, jewelry, and sometimes makeup. Being a female, I know a lot about brand name buying versus bargain buying. I am an expert at both. And one time I bought the wrong stun gun because I bought it from a no-name, untrusted website. They deceived me with their pretty webpage and false words; so, I am compelled to tell my story.
