Why Slow Cooking Liners wins, and what it beats

Every grade on this page is one sum. A category starts from a baseline, each disclosed material or coating adds risk points, and each thing the brand or a third party has published takes them away. Below is that sum for the winner, then for 3 products it beats, so you can see exactly where the 75 points between the top and the bottom of this slow cooker liners ranking come from.
