The zapper you linked looks like a very good one but not as likely to be able to be easily tucked out of sight under clothing as the "world's smallest". With the world's smallest you only have wires, a battery & the clips, and the electrodes. If you want you can add the copper tubes. It just all depends on what you want for your purposes & life style though.
Honestly I don't remember exactly how I coordinated Blessed Herbs and the parasite killing, but I do know I had been killing parasites for awhile before using BH and that all the parasites were not gone. BH didn't, for me anyway, seem to expel any more parasites than I had already been getting out daily. But I wasn't using it as a paracide, only for what it is really designed for, to remove mucoid plaque.
Yes, it is pretty creepy to see those awful things in the toilet, but as they always say here, "Better out than in."
It starts to be fascinating in a grim kind of way. You may find yourself searching the parasite photo gallery zone here asking, "What in the heck was that??!"
You are blessed over most in the population per my opinion.
Most people are walking around clueless that they have those little snakes inside them, eating them alive, leaving their excrement to poison their systems, etc. so naturally they are doing nothing to get rid of them. Hopefully people will start to catch on more and more in time, but as for us on Curezone, we are all glad to know now.
