    This product is for…

    Athletes who want accurate HR data without the discomfort, chafing, or maintenance hassle of a chest strap. Hosts mention running, biking, rowing (Concept2 ergs), yoga, paddle boarding, and skinning as use cases.

    Worth noting…

    Tattoos can interfere with optical accuracy, and one host flags a lifespan of roughly 24 months. It's rechargeable via a dedicated cable, not a replaceable battery.
