Ok, it' a zapper, but does it work? Why do they have deluxe and super-duper models on zapperplans.com? Do the super-duper ones work better or not? Do the zappers kill the worms inside your body so they don't bore holes through your skin trying to get out or does the zapper drive them out of your body however they can get out....anus, #1, mouth, nose etc. etc. etc?
