"Catching a cold or the flu at the very first symptom is the time to use a zapper" I had already been zapping for over a week prior to catching the flu bug(7-20-7-20-7) and then some.alternating between hands and feet.
I had felt really great to say the least. Then my kid caught something nasty from school. I kept in my head, this bug is not gonna get me but, it did for some reason. even with extra zapping as a precaution. I figured a higher input voltage could up the output voltage and get this bug running scared but no go.
Perhaps it was the 30.000hz. from my readings is supposed to have more of an effect on the immune system as apposed to the lower frequencies that are targeted to killing bugs.
Oh and I havn`t stopped zapping , been doing it still everyday since it arrived. I am very enticed to try out the other frequencies just too poor atm to shop for these things.
