>- Did you put the positive directly on the skin or cover it first?

I always cover my electrodes with a single layer of paper towel that has been soaked in salt water.

>- What about the negative, just hold in one of your hands?

That is what I do.

>- My basal cell is on my right shoulder, upper back area. Also I have the Auto-Zap, will this work as good as yours?

I doubt that the Auto-Zap is anywhere near a match for the ParaZapper MX but it still should be beneficial.
