freelastchance, why in the world would you discuss this with people that use the zapper? of COURSE they think its safe.
however,
i asked my father, an electrical engineer, this question about danger from amperes vs volts...
he said, think of an ampere as the swiftness of the flow of a river. think of the voltage as the depth of the water. you can drown if the water is too swift, or if the water is too deep.
