I just ran across your site and I couldn't resist the call to enlighten you on another use for this "zapper" or Tens Unit as they are called. I used mine as a negative reinforcer o stop smoking crack cocaine. It worked like magic! I quit smoking in one day! I also stopped smoking in three days and alcohol in two! It also got me over my break up with my ex-wife in one two hour session! Good luck to you. Please join my group at
