"Regular handheld copper pipe zappers work better. The Terminator takes a lot longer to work in my opinion and cost a lot more than most of the other units. I like the 3 frequency zappers on ebay. They start at $40, very reasonable."
Problem with the pipes is that you can't do anything else while you sit there and hold them.
What about Hulda Clark 's model with the wrist straps?
Also, which $40 ones off eBay? The tendollarzappers?
