HEllo,
I am not convinced that the zapper you sell is "a better zapper"
I do not understand what all this worry is about the pennies turning green on the terminator. They only seem to do this the first couple of times that you wear it..then they just darken a bit and need to be cleaned now and then. Many people report great results with this zapper. If there are concerns about copper, there is one man who sells the terminator and can cover the pennies with silver for an extra $50. I do not see the need though, as never does Don Croft, who made the terminator in the first place.
