I just replaced my Peloton heart rate monitor, it stopped working after less than a year. I tried replacing the battery and nothing. It also disconnected a lot. Otherwise it was fine and seemed accurate. I just bought this one and like it so far and it’s fully integrated with Peloton. Comfort with both was never an issue.
