Descriptions of the device in mainstream media note its US$20,000 price tag and the improbable nature of the claims made for it.{{cite web |url = http://www.badscience.net/2008/08/bill-nelson-wins-the-internet/ |title = Bill Nelson Wins The Internet |first = Ben |last = Goldacre |authorlink = Ben Goldacre |publisher = Bad Science |date = August 9, 2008}} It has reportedly been used to "treat" a variety of serious diseases including cancer. In one documented case, undiagnosed and untreated leukaemia resulted in the death of a patient.

The website Quackwatch posted an analysis of the device by Stephen Barrett which concludes: "The Quantum Xrroid device is claimed to balance 'bio-energetic' forces that the scientific community does not recognize as real. It mainly reflects skin resistance (how easily low-voltage electric currents from the device pass through the skin), which is not related to the body's health."{{cite web|url=http://www.quackwatch.org/01QuackeryRelatedTopics/Tests/xrroid.html|first=Stephen | last = Barrett | authorlink = Stephen Barrett|title=Some Notes on the Quantum Xrroid (QXCI) and William C.
