Congratulations on your success with this device.  If your experience is 
anything like mine then your benefits are just beginning.  The pain of a 
devilish heel spur (one which the physician described as "a whopper" and for 
which I had 2 cortisone shots (refused a third), was gone in about one hour of 
use of the zapper.  I had sat down to read while using the device for the first 
time and when I arose to get water, I was half way to the kitchen when I 
realized that I was not holding onto things to lessen the pain.  Whoop te do!!  
I zapped day and night after that and actually thought that might be the only 
benefit I would get.  However, after 2 to 3 weeks the extreeeme fatigue I had 
been experiencing for some time was gone.  I am much stronger now, but the 
unbelievable fatigue was gone quickly.   My son's acne which was pretty bad,, 
was gone in less than a week.  Redness gone in about one hour and the rest was 
healed up in less than a week.  My
 uncertainty about time involved is mostly because it has been close to 15 
years since these things took place.  I have used a zapper nearly every day 
since then.  My first one was his original one--$50.00 and a 30 day money back 
guarantee.  Best money I ever spent.  I keep a spare on hand at all times and 
keep a large supply of 9 volt batteries at all times.  I refer to the zapper as 
my immortality device.  So far, so good.  :)  Best wishes to all.   pj
