    Heart rate measurement without frills

    For me, the OH1 is the ultimate in heart rate measurement.
    Chest straps are accurate but terribly uncomfortable and slip. Optical sensors on the wrist are useless in winter, especially in sub-zero temperatures, the blood     flow in the wrist is not great (->ungau) and also the wrist has to be free of fabric.
    I don't notice the OH1 at all when I wear it, it's small and not a problem in winter as I can wear it under my running clothes. I use it with my iPhone and Polar Flow or Strava. Works great.

    Recommended purchase

    I use the OH1 with the Garmin Fenix 5s as an external HR sensor. The optical measurement with the sensor built into the Fenix works very poorly for me and my skin reacts allergically to a heart rate belt.
    I wear the OH1     on the upper part of my forearm. It works perfectly here. Compared with the heart rate belt measurement, there is a small delay in the display (a few seconds). 

    Pro

    • Works perfectly even with Garmin watch.
    • Is skin-compatible.

    Contra

    • Not useful for HRV analyses.
