I currently own the 6X Pro Solar, having upgraded from Apple. I also owned countless other Garmin watches, including the F3, F3HR and F5.
I will still keep using my 6X Pro from time to time in case things change for the better. Sadly, in my experience, the HR monitor is simply not up to scratch for daily stress/body battery/calories tracking.
Garmin’s continued silence on the matter means to me that they haven’t been able to fix this as they did try when the outcry began. GPS accuracy has gone downhill for me after the past few GPS software updates.
Hopefully the situation improves for everyone’s sake (unlike the mess of a product called Edge 830, which I owned and sold twice)
