Editorial Policy

Our editorial system uses three labels: Established, Claim and Unverified.

Established

Information supported by reliable references or ordinary technical principles.

Claim

A statement attributed to a seller, inventor, promoter or other source. Attribution is not endorsement.

Unverified

A material claim for which we have not found adequate independent validation.

Corrections

Time-sensitive commercial details should be rechecked and pages updated when evidence or offer terms change.
