Expert Review Summary
Our clinical assessment and verdict for each device
Ozeri Touch Total Body Scale (ZB13-W)
"Good for occasional weight checks, but absence of connectivity and limited accuracy make it less appealing for data-driven users."
Over 4 weeks with 20 users, the ZB13-W displayed weight error ±0.28 kg and body-fat error +6.0 % vs DXA. Without Bluetooth or Wi-Fi, all metrics appear only on the backlit LCD. Glass platform tolerates up to 200 kg but showed fingerprint smudging. Lacks cloud data so longitudinal tracking must be manual.
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.
