Replaced my old HRM with the new HRM 600. Works great and not much difference in fell of weight. Will be nice to be able to wash strap and replace strap while keep ing the rechargeable body.
I recently bought the HRM 600 to use with my Forerunner 265S and was excited to start using it but, unfortunately, the HRM 600 won't stay connected to the watch for more than 30 seconds. I was able to pair the devices (after waiting over an hour for software updates to finish downloading) but the watch basically loses the connection every time I connect them after less than a minute. If this is supposed to be Garmin's top-of-the-line HRM -- and it won't even connect with a brand new Garmin watch -- then my advice would be to go with a different brand. Knowing what I know now, that's what I wish I'd done...
I really like it over the other, I think is better measuring indoor speed and others metrics also the concept of battery charging also way better if the strap get damage is more easy to replace
I have been using this band for over a month while running and biking without any issues. This was an upgrade from my older band that used to work with batteries. This new band uses usb c and connects super fast
