Great for sleep tracking. Mediocre for everything else

I tested this fitness device for two full days together with another 2 devices (and the smartphone too for step count). While the others were basically in line for heart rate and steps, this one was often exaggerating by 30 to 40 % - especially steps. The good feature instead is the sleep tracking. Well done the app and reasonably accurate the track. The device looks cool and light but accuracy is not among the best qualities. Returned
