Does that include the bolt cutters? Do you realize that $23 for something is less than $45? Do you really need 3 of them? Do you also realize the ROP working is even questionable? Think bro and save your $$$.
Is it the voltage that gives the effect or the zinc? I have read that another metals can be used. Can someone explain me in mathematical terms how this voltage thing works.
It's to do with the difference between the two metals used. I don't remember the exact scientific explanation but it involves a conductivity gradient (or something like that) causing a current to flow from one metal to the other when a circuit is formed (by your skin).
