    2 weeks with the Instinct 3, better data than my Apple Watch. Love the different customizations. Great everyday watch!

    Inaccurate HR readings

    16 days ago
    HR rate sensor is inaccurate. Shows 90 when strap based monitor shows 150hr on my bike rides. I also had a chance to compare it to two different straps. Tightening the watch wrist band makes no difference. It’s essentially a piece of junk I’m returning

    The watch is literally every that I wanted in a fitness tracker with some bells and whistles for the profession. The Ruck app should honestly be spread across more platforms and I appreciate the light that I use daily. This watch is my new favorite in the line up. Ultras are too easy with the tracker and display in the watch face.

    Would be 5 stars, but for some reason the ‘Dexcom’ CGM app it not permitted to work on this watch. Come on Garmin make it compatible.
