HEALBE GoBe3 biosensor — the only bracelet with automatic calorie and hydration tracking (full set). A dream for biohackers, athletes, and anyone monitoring their figure. No more manually weighing food and logging grams into apps: the bracelet uses patented FLOW technology to read glucose absorption and calories directly through the skin. Unique features: automatic calorie counting (absorption/burn); real-time body hydration level (reminds you to drink water); emotional stress and nervous tension index; sleep phase monitoring and recovery quality; heart rate, steps, distance. Package: original branded box, bracelet, original magnetic USB cable. Battery is excellent (charged to 100%, screen is clean). Note: there is a minor surface scratch on the edge of the glass (does not affect display or touch at all, price reflects this). Price: 170 GEL (new ones cost from 550 GEL / $200 in stores).
