The newly improved 2nd generation Ozeri WeightMaster (440 lbs / 200 kg) Bath Scale with BMI, BMR and 50 gram Weight Change Detection was designed and engineered in the USA to provide a comprehensive yet simple weight management solution to measure and track your weight. Featuring Auto Recognition Technology to track the progress of up to 5 unique users, the Ozeri WeightMaster weighs up to 440 lbs to the nearest 50 grams (0.1 lbs / 0.05 kg) a 100% improvement from the first generation’s 0.2 lbs / 0.1 kg graduation. The new WeightMaster now displays both your BMI (Body Mass Index) - a measure of your body fat based on your height and weight, and your BMR (Basal Metabolic Rate) - an insightful measurement that indicates the amount of calories you need while at rest, in order to maintain your current weight. Embedded with Ozeri’s innovative Weight Change Detection, the WeightMaster displays your “net weight change” from your last weigh-in (L1), the average of your last 3 weigh-ins (L3), and last 7 weigh-ins (L7). For users who would rather just focus on their weight trend without worrying so much about the actual numbers, the WeightMaster features Color Alert Technology, which simply displays your weight change in a GREEN illumination for weight loss and RED for weight gain, providing a visual form of intuitive feedback. With built-in intelligence, the new WeightMaster requires no complicated synching and spares you the data connection failures common to more expensive wireless and Bluetooth alternatives. Precision engineered and durably made, WeightMaster auto-calibrates with StepOn technology and auto-powers off to preserve battery life. The Ozeri WeightMaster (440 lbs / 200 kg) Bath Scale with BMI, BMR and 50 gram Weight Change Detection is made out of impact-resistant tempered glass, and equipped with non-slip scratch-resistant feet that won’t damage flooring. Ships with 3 AAA batteries included, and backed by Ozeri's 100..
