Source hierarchy
- Manufacturer product page and specifications.

Accuracy
Before a product is recommended we record its exact model, current or discontinued status, key specifications and the date we checked. We re-verify on updates. If a fact changes, the ranking is reviewed. See our fact-checking and corrections policy.
Health and safety topics
For products that touch on health, recovery or injury, we keep guidance general, point to qualified professionals for personal advice, and avoid medical claims we cannot support.
