Hi friend lam dinesh today I want share my experience about fitbit Blaze smart fitness lam using is bit since five month.it is very useful and I buy is product in online and my first look and feel is very premium and really fits is very nice on any hand. It is a smart device and can also be used as a watch to check time.it really calculates the distance travelled, calories burnt, sleep monitering, heart rate monitering, exercise schedule and all other necessary stuffs needed for fitness maintaining. If you are going to gym then a fitness band is must but this fitness band is comparitively but it is cost is more than other fitness band which comes for way too lower price but with same specification. And like it friends.
