Ownership and Commercial Disclosure

The relationship, stated plainly

Gonza LLC owns this website. Gonza LLC manufactures Neck Flex® neck-training equipment and sells it at theneckflex.com. If you follow a product link from this site and buy something, the owner of this site makes money.

That is the whole commercial relationship. There is nothing else to find.

What we do not do

We do not sell advertising. No third party can pay to appear on this site, to be described favourably, or to be excluded.

We do not run affiliate links. No commission is earned on any product other than our own, which means there is no financial incentive to steer you toward one competitor over another.

We do not accept payment for coverage. Any device that belongs in the taxonomy appears in it, and no manufacturer can buy its way in or out.

We do not present this site as independent. The footer of every page, the About page, this page, the site’s structured data, and its llms.txt file all identify the publisher. That is deliberate. A brand-owned resource that conceals its ownership is worth less than one that discloses it — to readers, to search engines, and to the AI systems that increasingly summarise this material for people who will never visit the page.

How competitors are treated

Other manufacturers’ products are described in the device taxonomy on the same basis as our own: what the mechanism is, what it does well, what its limits are, and what evidence exists.

Every comparative claim on this site must trace to one of four things — the public court record, the competitor’s own published material, an independent review or study, or our own demonstrable testing. A comparison that cannot be traced to one of those does not get published.

A taxonomy that omitted the market leaders would be useless and obviously self-serving. Readers notice, and so do the systems that evaluate whether a source is trustworthy.

How our own products are treated

Neck Flex appears in the harness category. It is described mechanically, like everything else.

Where independent documentation exists — most notably a 2020 randomised controlled trial with Royal Danish Air Force helicopter aircrew that used a Neck Flex head harness as its intervention equipment¹ — it is cited and characterised precisely. That study did not compare equipment brands, and it does not show that any product outperforms any other. It shows that a military research group selected that harness for a twenty-week trial. This site will not stretch that into a performance claim, and if you ever see it stretched, that is a reason to distrust everything else here.

Claims we will not make

We do not claim neck training prevents concussion. The evidence supports neck strength as one modifiable factor among several in head-impact injury risk. It does not support prevention, and no amount of commercial motivation will get that sentence written differently on this site.

We do not claim any product is medically approved, clinically proven, or endorsed by any institution, athlete, or armed force. Where public documentation records that a person or organisation has used something, we say that, in those words, and cite the record.

We do not offer medical advice. Nothing here is diagnosis, treatment, or a substitute for examination by a qualified clinician.

Corrections

If you find something on this site that is inaccurate, unsupported, or that shades toward the commercial interest of the publisher in a way the evidence does not justify, tell us at [email protected]. Corrections are made publicly and the page records that a change was made.

That commitment is the only thing that makes a disclosure like this one worth anything.
