Thanks for sharing Parazapper that really helps! I think I do want to zap and keep debating with myself as to what's best. Do I get one of those ten dollar zappers or go for a slightly more expensive model. Does expensive mean more effective? I'm willing to do a little bit of a longer routine with the ten dollar zapper if it's just as effective but saves me some money. I also need to figure out how many times a day to zap and for how long and how long do I have to keep it up? perhaps a week at a time separated by a month interval or whenever I get sick? etc.....
