Bought the watch during the sale from <20K. The features on the device is simply superb. The watch face makes it look really cool. The battery life is not great, but not bad either. With a fair usage you are looking at average of 2 days. It takes around 1.5+ hrs to charge the watch. The watch is sort of big in size (In comparison to other smart devices), so might not suit people with thin wrists. Its also seems to be heavy watch on paper, but on the daily use it does not feel heavy. As far as the fitness side is concerned, it's an awesome device to monitor steps, running and cycling. I am not too sure how comfortable it will be to use it for workouts and sleep tracking keeping the size and weight in mind. Overall happy with the purchase!
