Editorial standards

Manufacturer figures remain attached to their exact model, method and conditions. Generic photographs identify physical features rather than the currently recommended model. AI-generated cover illustrations are marked as concepts.

We use manufacturer documents, named-source photographs and explicitly labelled arithmetic examples. No hands-on product tests or unverified current prices are presented. No advertising, affiliate programme or analytics account is configured.

Archival equipment photographs identify physical forms. They are not current purchase recommendations or our own product tests. Proportional WebP resize, no crop.
