Etekcity ESF-551 Smart Fitness Scale review

Etekcity's ESF-551 is a $31.99 Bluetooth scale built around the VeSync app. Its 4 electrodes estimate 13 biometrics: weight, BMI, body fat, visceral fat, muscle mass, protein, bone mass, body water, skeletal muscle, metabolic age, BMR, subcutaneous fat and fat-free weight. The feature that sets it apart at this price is Zero-Current Mode, which turns off the bioelectrical impedance current through the app for pregnant users and people with pacemakers or other internal medical devices. Baby Mode tracks a child's or pet's weight, and a light item mode weighs objects from 100 g. VeSync supports unlimited users and syncs to Apple Health, Samsung Health, Google Fit, Fitbit and MyFitnessPal, and it can connect to Alexa for voice answers. The 6mm tempered glass platform holds up to 400 lb. It carries a 2-year limited warranty, longer than Renpho's 18 months. The trade-offs are Bluetooth-only syncing and a plain LED readout without on-scale trends.
