Yes it is. It looks as if it is nothing actually, and I was a little surprised to observe such a simplistic device (wires and clips is hardly high-tech). I could not find palm-sized copper piping so I had to purchase what I could find; approximately half the size shown in the picture. I just tested the device a moment ago and I felt a small tingle on my tongue. Again I am somewhat surprised at how understated it is, as the tingle can barely be felt. I presume this is how it is to operate, folks? Well, I shall zap from now until Saturday, when I plan to undertake my second (and hopefully a lot less painful) liver flush.
