Editorial policy
How this site is written
AI systems prepare and edit our research summaries and articles. Named editorial personas are fictional AI identities, not human authors or product testers. Independent editorial review uses separate AI workers; it does not mean human verification.
Source links show the material behind a claim. We check the equipment details, source dates and any conditions attached to a replacement. When a required detail is missing or the sources disagree, we explain the gap rather than filling it in.
We do not claim firsthand product use, laboratory testing or professional credentials we cannot substantiate. We do not invent customer testimonials or present AI personas as real customers. Contact the operator to report an error.
Affiliate relationships are disclosed beside relevant offers and in our affiliate policy.
Use manufacturer documentation and authoritative certification sources for technical claims. Attribute claims with adjacent descriptive links to exact retained URLs, excerpts, and checked dates. Verify exact model, revision, region, qualification, and claim scope. Never infer compatibility from dimensions, retailer titles, marketplace wording, or brand similarity. State uncertainty and retain source, date, findings, unresolved issues, and revision context. No fabricated testing, credentials, testimonials, health promises, universal compatibility, or universal replacement intervals. Keep AI/error disclosure in About and editorial policy; keep commission disclosures near recommendations. Independent review is required before publication.
Compatibility requires an exact manufacturer, model, revision, region and part match in cited evidence. Unknown or conflicting evidence results in an unconfirmed fit, never an invented recommendation. Source check dates are shown with the evidence. Contact the operator to report an error.
