Garmin HRM 200 Heart Rate Monitor with Accurate Heart Rate and HRV Data

I can't see where it adds value over my Garmin watch

Honestly I can't see where it adds value over just my Garmin watch. It says it's tracking, then it just goes away and my watch behaves as it always has. It seems like my last one showed it's reading on the watch during the workout. This one shows nothing on the watch or the app. It wasn't worth it for me.

Garmin HRM 200

It works flawlessly, and accurately. The easily replaceable battery is a godsend. A very good unit and seemingly high quality construction.

Very happy with heart monitor. Just what i expected
