I started to get very nasty Rash/itching/bruning from zapping while using wrist strap for my super zapper delux. I tried different ways to solve this problem,but with no luck ,but finaly i reached to a good one ,that will work only for 7/20/7/20/7 programed zappers, and thats how to do it;

start as usual using the straps but remember the location of the black and red wire ends that hooks on your wrist straps after 7 mins the zapper should indicate the first active zapping cycle the ,now disconect your wires from the wrist straps and remove the straps wash your hands with cold water and do whatever you want leaving the zapper on (pause) which should last 20 mins,then hook them again after wetting your straps with water and revers the location of the red and black leads ,then the 2nd 7 mins cycle starts again then repeat same like before untill you finish the last 7 mins active cycle ,this should have the following benifets;
1- no rash/itching /burns.
2- frees you to do any thing in the 20 mins pause intervals without having your hands tide,e.g i sent my kid to school (near by) ,second one i shaved my beard(morning ritual).
p.s i hope this will work for your skin and your zapper .
pls keep me posted on your experience if you try it.
merry christmas and happy new year.
