# DataDesign

> DataDesign surveys published expert reviews and manufacturer specifications for gadgets and electronics, with a source behind every claim.

## How to use this site

- Every page states a bottom line first, then the evidence, then a numbered source list.
- Consensus scores are computed from published ratings by documented, deterministic code, not by a model. Method: https://datadesign.one/methodology/
- We do not test products. Claims are attributed to the outlet that made them.
- Each page has a Markdown twin at `<page-url>index.md` and machine-readable data under `/data/`.
- The structured data is CC BY 4.0: reuse it with attribution and a link.

## Comparisons

- [Logitech MX Master 4 vs Logitech MX Master 3S](https://datadesign.one/compare/logitech-mx-master-3s-vs-logitech-mx-master-4/) — updated 2026-09-22
  Get the Logitech MX Master 4 if you want its haptic Action button and slightly larger click buttons, and don't mind paying about $20 more at launch; get the Logitech MX Master 3S if you want the same core shape, battery life, sensor resolution and click noise, which Engadget says carry over unchanged, for less money.
