I use a zapper called Z4eX EXTREME 3 Frequency Hulda Clark Zapperit has very nice straps that go around the wrists, and I also got copper pipe electrodes for it but haven't used them much. I don't have any illnesses to speak of to make claims for healing, but that may be a testimony in itself. Last time I "caught" a cold from the grandkids, I never stopped up or had a runny nose but did get a slight cough after several days, and did need to use a little CS in my nose to open my sinuses at that point, which it did quickly, but I used to get terrible sinus infections with colds, and that did not happen.
What I do use it for is my insomnia, frequently by putting on the electrodes when I am not able to sleep: it will help, though not always. What I like is that I don't have to wet the electrodes and they don't tingle or burn. I also have a Sota Silver Pulser which did cause redness and irritation, even burning sensations, and needed water. I have to say I stopped using it when I got the Z4eX from ebay. Has anyone else tried this zapper?
