    Thanks for your feedback.

    The Polar WearLink+ heart rate transmitter comes with a strap that is one size fits all. The transmitter features user-replaceable battery (CR-2025) with a 2-year expected lifespan.

    The heart rate transmitter weighs approximately 1 ounce, and the strap weighs approximately 1.5 ounces.

    The transmitter uses a coded 5 kHz transmission, ensuring that your Nike device finds your heart rate signal.

    Note: The Polar WearLink+ heart rate transmitter is compatible with the Nike+ SportWatch GPS, the Nike+ SportBand, and the Nike + iPod experience on iPod nano (generations 5, 6, and 7). If you are looking for information about using a heart rate monitor with Nike Run Club, please click here.
