How we choose products

Every product on a comparison page has passed the same minimum standard: an average rating of 4.0 stars or higher, at least 25 customer reviews, available to order when we last checked, data captured within the last six months, and at least half of the category’s specs known.

Products that pass are ranked by a Best Score from 0 to 100. It combines the rating adjusted for review count (35%), how well the specs fit the page’s job (30%), review volume (15%), warranty and brand record (10%), and sales rank (10%).

A rating based on few reviews is pulled toward the category average, so a 5-star product with eight reviews cannot outrank a 4.6-star product with thousands.

Editors can pin or exclude a product, and every change is recorded with a note. Specs come from manufacturer spec sheets and retailer listings. Where sources disagree, we show the note beside the value.
