Thank you! You are so kind to give me so much info. Especially appreciate the encouragement that it is a good zapper.
Just one more Q. please. I did not know you always had to have those metal tubes. Guess I'll buy some copper ones on ebay but until they get here, can I just press those little metal ends to my skin, or inside the palms of my hands? Guess not because of the wet towel issue, but thought I'd ask.
Actually, I have already used them that way today, after I first got them. Oddly (to me) it did feel as if maybe "something" was happening.
