The only complaint (con) of the 970 that I can think of is
The button sound and the sound when you start running.
All the Garmin Forerunners I've owned have made the same sound
910xt 920xt 630 945 955
When I stood at the starting line of a marathon, I felt a sense of kinship when I heard the same Garmin sound from my watch with other runners all around, and I thought it was Garmin's heritage
However, the 970 lost its heritage
The sound of the 970 is just the sound of a smartphone
I want to hear Garmin's traditional sound, even if it's not the old 8-bit sound (even if it uses high resolution)
We are runners, and give us back the sound that is the identity of Forerunner users!
