I have purchased this fitbit charge hr band from ghaziabad for 12000 rupees.
It has many things for experiencing like at every point of time it will help u know your correct heartrate while you are resting, walking or running.
It will also help u know about how much steps , stairs you have walked in one day.it has very small display and looks like simple wrist band.
U have to charge it for 2-3 hours for running it continously for 5 days.it is very light weight and fully comfortable.band is very good looking.u can also use this band to record workouts using exercise mode.it is total value for money.go for it.
