I have just purchased a zapper from the zapper guy through some other site and hope to be receiving it shortly. I too like the previous poster was overwhelmed by all the different models available. I made a lot of researching before finally going ahead with this model (Zapper C31 w/wrist straps and belt clip).
Eventhough the theory behind the zapper makes sense to me, you still have to be careful when shopping around - it can be so easy for someone to make money of of this, as it is when the promise of better health is involved and it seems so good we are blinded by our own hopes and desires.
Paulette, what kind of effects did using the zapper have for you. What I mean by this is how did you feel before being introduced to zapping, and how has zapping affected your health? Have you experienced a 180 degree shift in your physical health? How do you know that it is working for you?
PS: You mentioned that you had bought another model. Would that be the Super Zapper Deluxe 2003? Have you felt any different since using this new model, as compared with the old zapper you had? I too was thinking of purchasing that model but felt I should first start with the "entry level" zapper and see what it does for me before moving onto the the Cadillac.
