This will my my first time Zapping so a bit anxious, I have this on order purchased from the US having time to get past my nerves. Can some body share there first experience using a Zapper with me plz. This might help me see light my friend uses one he says some thing about he feels tingerling over his body while being used. I am amazed at what a Zapper can achieve what with killing Viruses, Molds, parasite and more.
