Since no one else seems interested, I'll go ahead and transform my comments into an answer. Not sure things will meet the site standards, but I'll let y'all decide.
First of all, the Australian government doesn't seem to think much of the rings.
Quote (bolding is mine:)
Additionally, the company's website, www.nosnor.com, claimed the ring had a 'proven history of successful drug free treatment of snoring' and was 'Tested and recommended by a Physician'.
The ACCC raised concerns that these claims were likely to mislead consumers to believe that the product had proven medical outcomes in treating snoring, sinus, restless sleep and insomnia when this was not so.
"When a product is heavily marketed and sold at major retail chains, consumers tend to give a certain legitimacy to the product and the representations being made," ACCC chairman Graeme Samuel said today.
"Suppliers of alternative health services and products must ensure that they are not overstating their supposed benefits while skirting around the fact that there is little or no supportive medical or scientific evidence."
ATQOL has acknowledged that its conduct may have contravened the misleading representations sections of the Trade Practices Act 1974.
It has provided the ACCC with court-enforceable undertakings that it will:
- not make absolute representations that the Anti-Snor Ring will stop snoring or relieve sinus problems, restless sleep or insomnia
- not represent that the ring has a 'proven history of successful drug free treatment of snoring' unless it has caused clinical trials to be undertaken to prove such a history
- not make any representation that the ring has been tested, approved or recommended by a health professional unless that health professional has undertaken testing in accordance with accepted standards for the design, conduct, records and reporting of clinical trials
- amend the ATQOL website and any current and/or future advertisements or publications to remove the incorrect representations
- ensure that all future representations made in the promotion and/or sale of the ring comply with the Act, and
- implement a trade practices law compliance program.
By implication, there are no acceptable studies showing that the rings are effective.
Note in particular the bolded section above:
ATQOL has acknowledged that its conduct may have contravened the misleading representations sections of the Trade Practices Act 1974.
The manufacturer admits to not having (or not having provided) adequate proof of effectiveness.
Second, similar rings include a disclaimer that indicates they have no proof of effectiveness and therefore are "are not intended to diagnose, treat, cure, or prevent any disease or health condition."
That comes from the Amazon sales page originally linked in the question.
Full quote from the Amazon page (bolding original:)
Legal Disclaimer :
Statements regarding dietary supplements have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease or health condition.
Which says they haven't gotten FDA approval - even though if their claims about effectiveness were true they could have done.
Summary:
- No verifiable proof it works
- Not bothering to officially prove it works by getting it registered with the American Food and Drugs Administration.
- Accepted sanctions from the Australian goverment rather than try to prove it works
