Is one brand of Hulda Clark Parasite Zapper better than another?
ParaZapper ™ provides a stronger output than many other zappers and uses less power from the battery thereby making the battery last longer. Some other zappers cycle on and off automatically. ParaZapper ™ does not because we feel that the user should have control over the length of time that they zap due to individual differences. Otherwise, most zappers perform the same function, which is outputting a 9-volt square wave at some frequency. A lower frequency of 2.5 kilohertz is probably better for some parasites as discussed above. ParaZapper ™ CCa definitely produces better results according to user survey feedback. For the absolute best results, use the copper footpads along with the copper handles.Beware of those who claim that their zapper is the best. Ask for statistical proof.
