I have not had any significant visible confirmations of parasites
existing my body since I began zapping. In my case, I suspect the results may be being skewed by various things, to include things that have been part of my daily regiment for many years, as well as changes I've added since I first started zapping.
There is one obvious benefit I've experienced, it was apparent within the first few days of beginning to zap for the first time, and it's not a benefit that I've seen mentioned or touted anywhere on the forums where zappers are beign advertised, and I've seen no other people (users) report this benefit; I've been a long time sufferer of GERD and heartburn, sometimes referred to as "acid stomach", in a cyclic fashion, when the cycle is down, I can go weeks and months without much problems regardless of what I eat or drink, when the cycle is up I can have heartburn and reflux daily for weeks at a time regardless of what I don't eat or drink. Since I began zapping, the visible symptoms of this maladay (the regualar heartburn) has been non-existant ! I say it this way only because I suspect that despite these obvious symptoms the underlying problem and hidden symptoms are probably still there (in my belly and abdomen ). Just to tempt fate and confirm, I stopped zapping for a about 2 weeks, and sure enough, the telltale signs of the onset of heartburn began to re-appear, only to go away again after re-starting zapping. I've been able to recreate this situation several times in the past 14 months, so I try not to go more than a week or so without some zapping. It's been suggested to me by one person on a forum far away from here that zapping is somehow helping to balancing/offset my body's pH, or in other words, reducing the acidity in my body / stomach...... who knows for sure?, I don't, but I'll be a regular zapper for this reason alone for the foreseeable future :)
