This is a great product albeit pricey at 14, 999 when I bought a month ago. It is now at 11, 999. The product is very good tracks steps, heart rate and sleep patterns. It has a weeks worth of battery life. It is not bulky and quite inconspicuous on your wrist. I had the Flex before this and now this one is a worthy successor. I only wish I had waited and bought it now for 3k cheaper rather than a month ago
