What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Withings Body Smart
Only one whitelisted tester, Tom's Guide, published a hands-on review of this exact model. Tom's Guide praised the polished companion app, easy setup and body-composition breadth, but flagged the $99/year Withings+ paywall on key insights. No lab accuracy benchmarks were run. (1 sourced review.)
Praised: Sleek, modern companion app with science-referenced explanations of each metric; Easy, streamlined setup plus automatic multi-user recognition; Broad body-composition metrics and 100+ third-party app integrations (Apple Health, Google Fit, Strava).
Flagged: Best insights (Health Improvement Score, Body Score) locked behind $99/year Withings+ subscription.
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, 4 lab-tested.)
Praised: Best fit for users already in Garmin's ecosystem (data syncs into Garmin Connect alongside activity stats); Solid, premium, well-built hardware and design; Consistent, accurate straight-weight readings.
Flagged: Expensive / premium-priced; hard to justify unless you're in Garmin's ecosystem; Companion app adds little context or insight on the metrics; Glass surface hard to keep clean; shows dust and toeprints.
