Methodology
How we score
Scores are calculated from listing specifications, not lab tests — and not from user ratings. Every number on this site can be re-run from the tables on this page.
The rules
- Each category has its own criteria and weights, fixed before scoring and published below.
- Each criterion is scored 0–10 from the listing specifications; the Spec score is the weighted average.
- Where a specification is missing, that criterion is dropped for that product and the remaining weights are renormalised — a missing spec never silently counts as zero.
- A value that comes only from the brand's own marketing is marked (brand claim) wherever it appears.
- Commissions never enter the formula. Links earn the same whichever product you choose.

What a score is not
A Spec score compares specification sheets inside one category. It is not a lab result, not a durability test and not a summary of buyer reviews. Where a pick suits you also depends on the best-for and skip-if lines, which come from the same attributes.
