What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Renpho Elis 1
Three whitelisted testers (Tom's Guide, Reviewed/USA Today, TechRadar) hands-on tested this scale, sold as the Renpho Smart Body Fat Scale / ES-CS20M and now branded Elis 1, and all recommend it as an accurate, easy-to-use, exceptional-value smart scale with a strong companion app (Tom's Guide and TechRadar count 13 body-composition metrics plus Apple Health, Google Fit, Fitbit and Samsung Health sync). Caveats: the display shows weight only, the platform is small, and it rounds weight up about 0.2 lb. (3 sourced reviews, 3 lab-tested.)
Praised: Accurate, consistent weight and body-composition readings in hands-on use; Well-designed companion app with 13 body-composition metrics plus Apple Health, Google Fit, Fitbit and Samsung Health sync; Exceptional value; among the cheapest smart scales tested.
Flagged: Display shows only weight; you must open the app to see the other 12 metrics; Rounds weight up in 0.2 lb increments and read slightly heavy against reference weight plates; Small platform can feel awkward underfoot.
