On May 29 I paid online for a blood electrifier, after emailing 3 times over 2 weeks he finally wrote back and said he sent it. I got it hooked it all up and the unit was obviously not working correctly. There was no adjustment to turn down the power, it was pulsing so strong that it was causing my hand to twitch involuntarily. The next day I tried to turn it on and then it wouldn't work at all. I emailed him saying I was shipping the unit back to him and was hoping he'd send me a new one as a replacement. Another 3 weeks have passed and I have asked for a replacement or my money back, to date still no answer. This guy is unprofessional and untrustworthy. I lost $100, don't make the same mistake with him.
