You may recall several months ago I emailed about my husbands severe reaction to the zapper. You both contacted me and eased the situation. Well, just want you to know my husband now zaps daily and the indigestion/”heartburn” he used to suffer from is gone. He was a bit nervous to try again as he was knocked out for 2 full days, but per your request, he started with 2 minutes and increased to 5. His body’s response proved to him that there is something to this zapper! And his health improvement convinced him of the zappers benefits. Thank you for making it and for your quick, knowledeable, and compassionate customer service.
