They do offer a 30 day money back guarantee, other than some shipping fees no harm in trying them?
But I pose the question, how does one come upon these Magic results? To simply say, “it works but we don’t know how”, what prompted the designer to even try whatever is in the tube? If these tiny tubes of dust make a notable difference, why not make them twice as big? Or round to incircle the whole wire? I’d be more comfortable if he claimed the tubes contained uranium 238 than to have no idea what it is. While it may work exactly as advertised, the manufacturer has done nothing to separate himself from other snake oil salesmen. i.e. “Its Magic! It’s mysterious! Read my testimonials!”, does not instill me with confidence.
