Yea, Didn't notice his web site address on the zapper before. http://store.zapperguy.net/

Mine has the same specs as the one he is selling today, but the new one might have better electronics in it.

Mine looks identical to his new one.

with only one alligator clip not sure how to use it. He doesn't provide any instructions because of it being illegal.

Can I assume the cloth wrist strap that is attached to one lead is for holding down one of the copper tubes?

He sell the wrist bands, and the alligator leads as a pair although the wrist bands are out of stock.
