EXTREMELY DISAPPOINTED in GARMIN’s HRM-Dual heart rate monitor. Despite the fact that I have the Garmin Fenix 5S which is supposed to be compatible with the heart rate monitor, the watch app does NOT list the HRM-Dual as an device option (to pair). I switched to a computer (as recommended by the Garmin website - this alone tells me this is an known issue but one that is not disclosed at the point of sale or in marketing) but that just told me to replace the battery. Wait a minute - this is a brand new device and I’m supposed to replace the battery upon opening the package?! Attempted to open the device - used a fine, small Phillips head - the screws will NOT come out. This is so frustrating. Extremely disappointed.
