Evidence controls the conclusion
Source evidence determines the conclusion. Advertising, commission rates and stock availability cannot change compatibility status, source selection or product ordering. Commercial relationships are disclosed where they apply.
No test claim without a test
We do not publish subjective “best” rankings, cleaning-performance scores or durability conclusions without a documented test method and original results. Manufacturer specifications are identified as manufacturer claims.
Changes and withdrawals
When source evidence changes, affected facts and pages are reviewed. A relation may be downgraded to Unknown, a commercial component may be withdrawn, and a material change is recorded in the page or change history.
