I think the skepticism is because the reply from RD is from someone who stands to benefit from the sale of their products. While that may be the case, I could hardly believe that such products would be mass produced, marketed, and sold based solely on the hyperbole of hobbyists observations.
While the article could offer no conclusive proof of benefits, neither could it prove any harm - in the summary the author simply stated to use at your own risk. Personally I have used it, but have observed nothing either way in benefits or harm.
