Finishes top run after run; capped at 3 slots per category. - A: Excellent. Strongly recommended, beaten only by the very best. - B: Good. A solid choice with real caveats worth knowing. - C: Fair. Acceptable in the right situation, outclassed at its price. - D: Weak. Hard to recommend when better options cost similar money. - F: Avoid. The evidence points you elsewhere. ## How to read this - Each category is researched in four independent runs, one per lens (expert consensus, value, reliability, community pulse). Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand. - LP is the product's points on this category's ladder. It is comparable within a category and not across categories. - Outlets is how many distinct outlets are cited for that placement. The per-product page lists each citation, and shows which of their links were fetched and confirmed before publishing. - Nothing is hidden: every product the research placed is on this board.
