I upgraded from the OG Garmin HRM that I’ve had for almost 6 years and there are several features that are vast improvements. Primarily, being able to recharge the device as opposed to changing the battery. The enhanced recording features give me much more data and accurate data to see more specific schematics of my running in which I can improve my skills. The comfort is great just like my older model but being able to remove the device portion when charging and wash the strap makes prolonging its life that much easier. Very happy with the new advanced HRM 600!!
I use the HRM 600 for heart rate training and find it more accurate than the Fenix 7S wrist monitor. Nice features include it's rechargeable and has the ability to record heart rate, steps, calories, and intensity minutes without wearing a Garmin watch.
If you train most days, the CR2032 (or similar) batteries found in most heart rate bands are probably the bane of your existence. They're pricey, changing them often jeopardizes the weather seal of the unit, and once their level start to fade, they give unreliable readings... without being obvious that the battery is dying. Finally, one that's rechargeable! As far as I know, the first and so far only one on the market. I can just pop it on the charger regularly - say once a month or before an long event - and I don't have to worry about the rest. No annoying batteries anymore.
I've been using it with my Garmin Fenix 6S watch and my NordicTrack X32 treadmill mostly successfully. I've had a data transfer issue once, but otherwise it's been doing a great job.
It uses the same charging plug as my Fenix 6, which is convenient.
Hopefully the band lasts, as despite cleaning it regularly that's usually what fails first on HR straps. But we'll see in a few years.
Connects easily to Peleton Bike. Great that it is rechargeable. Garmin has clearly focused on reliability and am hopeful this becomes true over time as earlier models were problematic
