There is a testimonial from Dr. Jeff Spencer who is the doctor for Lance Armstrong (who just won his 5th Tour de France). Dr. Spencer used the QXCI on Armstrong IN FRANCE WHILE HE WAS RACING. His testimonial/opinion about the machine is in an e-zine on the www.qxciscio.com website. I'll put a link below to it. It's issue #3. I'm sure they'd give you his email address or phone number so you can talk to him about it as a REAL person. By the way, REAL people use Hotmail, Yahoo, etc. too. : )
