Thank you for bringing this up david101, will allow me to make correction. The zapper I use to power my zappicator is the Zapper Digital from HC (blurred vision, fogged mind). Didn't want to buy their unit sold to go with zappicator, had to find ways to make it function.
I tried to use this zapper during sleep but couldn't sleep at all with unit attached to me. Even my T2 bothers me. I hang it within a few inches away from my head at night. Tried to wear it in loose socks under feet, no way I could sleep with this one too.
