So I have been running for health and keep my body shape for a while. Recently I decide to buy a Fitbit Charge HR -

or Fitbit Charge -

, so far I know they both work for tracking steps taken, and the calories consumed and burned. But I think I need more personal advice from runners who have been using this, also about the price I think they both got good deals, what make the price difference between these two styles? and which one is recommend?
Thanks.
