Ownership and Commercial Disclosure

The relationship

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.

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.

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.

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.

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.

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.

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.
