Zappers really work?

Hi All, I want to start using a zapper and was wondering if anyone can tell me that they have personal experience that it works? Also, I was originally planning to follow Hulda Clark 's protocol (zapping three times a day for seven minutes each time)but now I'm hearing about all these other things. Plate zapping, Zappicator etc... is there anything that is easy and effective without having to use the synchrometer for things and then zapping them a few at a time (like plate zapping)? Do these methods work? Thanks for any help or insight anyone can provide!
