Strengths

Reasons to shortlist it

  • Dual-frequency BIA at 50 kHz and 250 kHz
  • 25 body-composition indicators plus heart-rate measurement
  • Supports up to 36 family members with 0.1–150 kg measurement range

These are documented characteristics, not a claim of hands-on performance testing.

Compromise

Who should look elsewhere?

Xiaomi explicitly states this is not a medical device and results are for reference only. Cloud synchronisation depends on the Xiaomi Home ecosystem and a Bluetooth gateway; it is not a Wi-Fi scale.

If that trade-off conflicts with your priorities, compare an alternative instead of forcing a fit.

  • 16 body measurements including weight, body fat, BMI and muscle metrics
  • Wi-Fi and Bluetooth connectivity with unlimited app users
  • 50 g / 0.05 kg weight increments and 0.1–180 kg range

Main trade-offComposition metrics are consumer BIA estimates and can vary with hydration and measurement conditions; use consistent conditions for trends rather than treating a single reading as clinical truth.

  • Weight accuracy stated to within 50 g
  • Body-composition metrics including body fat, muscle and water
  • Wi-Fi and Bluetooth connectivity for up to eight users

Main trade-offBody composition and derived metrics are estimates, not a substitute for clinical assessment. Withings modes and app insights are most useful when measurements are taken consistently over time.

Evidence freshness

A date should tell you what was actually checked.

This product has deeper specification research. Australian Product Guide separates substantive review from retailer, source, image and price checks rather than collapsing them into one artificial date.

How APG assesses this product

Evidence, suitability and retailer context in one place

APG applies the same evidence, suitability, retailer and imagery checks across its maintained product catalogue. Where APG has a useful classification but not a manufacturer-verified fact, that distinction stays visible.
