Positives about the watch: price, brightness of the watch face, and battery life – stays charged for 7 days. When comparing to other fitness watch (Fitbit Charge 3) the heart rate, step accuracy and sleep is consistent.Cons about the watch. Can only connect with app, which I am not too thrilled about – stats not available on the website, calorie burn seems inaccurate, no gps tracking, sport settings are odd at least for me. It has the usual running, walking, biking but I would not use boating, gymnastics, basket ball or soccer. Again the calorie burn for these activities seems inaccurate.Overall, though, for a basic step, sleep heart rate tracker it works just fine. If you need or want more detailed information, then you would have to step up to a different tracker
