How we rank and where the facts come from

We compare published specifications, not hands-on experience. Requirements filter the set; the sealed published order is unchanged. The index uses fixed weights and gives missing specs a midpoint. That is an assumption, not evidence of fit or quality. Unknown details cannot qualify a match.

What changed: specs in this snapshot were checked July 2, 2026. This package includes no prior spec revision; changes to individual values cannot be established.

Before you buy

Why do some picks have no buy link?

Only exact models with verified Amazon listings receive links. Other models keep their place. A link does not establish current stock or price.

Does the highest rank mean the right product for me?

Start with your requirements, then compare the recorded differences. The published order reflects one set of weights, which may differ from your priorities.

What should I confirm before ordering?

Check the exact model, compatibility, current price and return terms. Published specs do not establish reliability, noise, comfort or ownership experience.
