I have been totaly into these things since I got my first Garmin 310xt. I dig them. I have had many Garmins, a couple Fitbits, which both broke, and a Samsung. I now have a Garmin Fenix 5 Sapphire. Paired with my HRM strap I can get some cool data. I never had a Polar or Suunto. Anyone have anything to add? I am a Garmin guy all the way if you haven't guessed that.
