I can tell you that zapping has been COMPLETELY INEFFECTIVE for me..
so before you spend 300+ dollars on a new zapper please know that the main proponant of bob beck in this forum does not have herpes and has not experienced any real relief from bob beck for herpes.
ps- read my recent posts if you need evidence. and remember, ALL SORTS of claims are made in books, on websites, by 'prophets' (some of whom are quite rich). It doesn't mean anything though until you actually find a real person WITH herpes who has found relief.
