## What reviewers say

**Garmin Index S2** — All four hands-on reviews (DC Rainmaker, TechRadar, Tom's Guide, Engadget) survived verification. Consensus: the Index S2 is a well-built, premium scale that gives consistent weight readings and shines mainly for users already inside Garmin's ecosystem, but is expensive and pairs with a companion app that adds little context. DC Rainmaker is the only source with measured numbers, and body-composition (impedance) accuracy remains disputed. (4 sourced reviews.)
