    This product is for…

    Runners and cyclists who want more reliable HR data than wrist-based optical sensors provide, especially those with small wrists or who train in cold weather where cadence-lock is a risk. Suits anyone who wants a low-fuss monitor they'll actually remember to wear consistently.

    Worth noting…

    Multiple hosts specifically flag it as a fix for cadence-lock, where a poorly seated watch misreads running impact as heart rate. Notes are uniformly positive, so no dissenting views to weigh.
