Review on 🏋️ Garmin HRM-Dual Heart Rate Monitor 010-12883-00 by Jacob Brasic

The main problem is that it doesn't transfer data. The sensor will predictably connect to any device, but you're lucky enough to get actual heart rate data from it. With four different apps, I only get a signal that yes, the sensor is connected, but the heart rate field is blank. Garmin support, which is slow to respond, just gives the same tiresome Bluetooth pairing instructions. It's a bit strange that they can't even figure out the problem from the screenshots (which I've shown here).
