Expert Review Summary
Our clinical assessment and verdict for each device
Eufy Smart Scale P2 Pro
"A low-cost Wi-Fi scale that delivers solid weight accuracy but only moderate body-fat precision."
We evaluated the Eufy Smart Scale P2 Pro over six weeks in a mixed-gender cohort. Laboratory weight standards and dual-energy X-ray absorptiometry (DEXA) served as reference methods. The device achieved excellent weight accuracy and acceptable body-composition precision for home monitoring, though its impedance-based fat estimates trended 5-7 % higher than DEXA in high-BMI users. Build quality is strong for the price, but the LED display is basic and can wash out under bright light. The EufyLife app is easy to navigate, offers a 3D avatar, and synchronizes reliably with Apple Health and Google Fit.
Withings Body Comp
"A feature-rich smart scale that pairs solid accuracy with uniquely deep cardiovascular insights, though its extras add cost some users may not need."
Across a six-week prospective study, 40 adult participants (BMI 19-34 kg/m²) used the Withings Body Comp alongside a Class III calibrated beam scale and dual-energy X-ray absorptiometry (DEXA). Weight error averaged 0.08 kg (±0.11), while body-fat and muscle-mass errors averaged 7.4 % (±2.1), which is higher than thresholds considered acceptable for research or professional athletes. Even so, the scale’s multi-frequency bioimpedance still captures directional changes that suit everyday trend tracking, and its vascular-age and electrodermal-activity (EDA) outputs correlated moderately (r = 0.46-0.52) with carotid-femoral pulse-wave-velocity and Sudoscan reference devices. No device-related adverse events occurred, and overall Body Comp supplies convenient core metrics plus novel cardiovascular and nerve-health indicators, albeit at a premium price compared with basic smart scales.
