[5] In 1992, Consumer Reports tested Kordich's Juiceman II extractor and concluded that other competitive models were easier to clean, cheaper, and worked better.

[8][9] For example, Kordich stated that he was influenced by the Gerson diet and was cured of cancer when he was 20 by consuming 13 glasses of apple and carrot juice each day.

[8][9] Stephen Barrett of Quackwatch noted that Kordich made far-fetched, nonsensical, and unproven health claims about juicing.
