New/unopened box. It was purchased from Amazon in 2016.
The sensor attaches and reads your hear rate. I had a watch that would then show the heart rate and it would also show on the cardio machines in the gym.
Happy to include the sensor but I don’t know if it works and it probably needs a new battery.
