How we score

Every product gets five sub-scores from 1 to 5, weighted into a score out of 100. We don’t accept reader reviews, votes or submissions; every score is ours.

• Evidence & honest claims: does independent research support the main benefit, and does the brand avoid overclaiming?
• Value: price, or true 3-year cost including required or typical subscriptions, against the category.
• Ease of use & upkeep: setup, maintenance, washing, comfort.
• Trial, returns & warranty: how safe it is to try.
• No lock-in: do you need a subscription to get what you paid for?

True 3-year cost = upfront price + 3 years of subscription (2 if year one is included). Optional subscriptions are included when most features depend on them; we say so on each page.

Unknowns: if a policy isn’t verified we give a neutral 3. If the price isn’t verified, value is 0 and we show “unknown.” We never estimate prices or specs.

Scores are editorial and based on published specs, pricing, policies and research. Unless a page says otherwise, we haven’t lab-tested the product. Affiliate relationships never change a score.
