Source Policy

We summarize factual information in our own words and link to primary sources whenever practical. Time-sensitive notes show when they were checked and should not be treated as real-time guarantees.

Confidence reflects source quality and freshness. If a source changes or cannot be verified, the related note should be updated, qualified or removed.

Images, names and quotations

Product and brand names identify the subjects discussed; they do not imply endorsement. Our publishing policy is to use original or appropriately licensed visuals. A source link alone does not grant permission to reproduce its photographs, product descriptions or reviews.

Price and availability comparisons

Compare the exact model and condition, included accessories, delivery destination, shipping, taxes and return costs. A dated listing is not a promise of current stock or the lowest price. Unknown costs must be identified rather than assumed to be zero.

Editorial review

AI tools may assist drafting and calculations. AI output is not evidence: factual claims must be checked against appropriate sources before publication. We distinguish sourced facts, estimates and editorial judgments.
