Its one of the best Fintness band ever I seen by the company lenovo. The band has an high grade dynamic heart rate moniter. It has best in class silicon food material band which is comfortable on hand and the best feature is comfortable on hand and the best feature is that it has an 0.910 led display. Its very user friendly any body can easily for all kind of people. It has also a function called remote camera through which you can clike photos remotely. Everythings is fine but the app is a bit confysing for the first time user. It has bluetooth 4.2 which really power efficient and gives battery back up of around 5days.
