Compared to the previous Instinct model, all body analyzes have improved. apparently the sensor has improved and so has the algorithm. The bracelet is worse than the previous version (the harder one does not adapt as well as the previous one). After a couple of weeks of use, a bug also appeared, the pulse oximeter crouched: a couple of resets for the device and the application and it started working again. Resting heart rate/normal activity heart rate measures well, but stress heart rate needs a heart rate belt as a companion if you want accurate information, probably the same with every watch.? Overall a great device, battery life is excellent.
Excellent features. Light and comfortable on the wrist. The camo pattern was "black camo" and not the light one, as in the product image.
