Its very useful smartwatch and has necessary functions such as Blood pressure measurement and ECG. It also has decent battery backup of 24 to 36 hours depending on usage, after a week the battery optimises itself and battery life increases remarkably. The only problem is that it gets heat up and automatically goes into flight mode whenerver you call only for 5 minutes on LTE networks. This makes LTE functionality not much useful. Although you can leave your smartphone at home if you are going out for only 2 or 3 hours. Overall value for money at price lower than 10k.
