When my health is so ill.When I treat from doctor.Doctor say me use fitness band and measure your heart beat and pulse rate.Then I purchase this fitness band from near by a store.But when I used this band in few days it became some issues like the pulse rate measure different and battery backup time.The look of this product not so good average.And other features are less than other fitness bands.In compare to its price it is not good.The style and designs of this product is not latest.The main problem is its rate count and battery backup time.
