I've had 3 sessions so far and, to be honest, I'm not quite sure what to think yet. I've also had treatments on a Biomeridian machine (one of the EAV Voll type of machines) and I think the Biomeridian machines are more effective. The QXCI/SCIO machines definitely have some interesting therapies built in to them but for a person who is fighting a serious disease or health problem I would recommend trying to find someone who uses a Biomeridian machine.
