Choosing between gt and gt2 stopped at the first because most of the functions of 2 I think are redundant and resource-intensive. Has some pros: Autonomy, manufacturing materials, functionality. Precise sensors: sleep, heart rate, pedometer. The oxygen in the blood was not measured. Some cons: a small bracelet, fastened on the last two or three holes on a man's hand. Soft cut NFC module, stress meter.
