Amazon is now offering the Etekcity ESF93 Smart Scale for $19.99 with free shipping for Prime members. Be sure to clip the $2 on-page coupon. This is nearly 25% off the regular $26 price tag and the lowest we can find on this model. Compatible with Fitbit, Apple Health, Samsung Health, or Google Fit via the companion VeSync app, it allows users to “view trends and track progress in one central location.” Using four built-in sensors, a blue, backlit LCD display, and a 6-mm-thick tempered glass, it can track 12 body composition measurements: “weight, body fat, body water, muscle mass, bone mass, protein, BMR, metabolic age, visceral fat, subcutaneous fat, fat-free body weight, and BMI.” Auto calibration, 30-second auto-off, unlimited member profiles, and a 400-pound capacity round out the feature set here. Rated 4+ stars from over 3,700 Amazon customers. More details below.
