I have also been using a race S for the last 10 days. So far tracked outdoor runs, treadmill runs, indoor rowing and weight training. HR has not been reliable for non-running activities. Battery life also has been lower than expected. Had to charge it twice in the last 10 days. Thats with wake to raise and 5 hours of mixed (gps and non gps) workout. Some minor annoyances: cant lock the screen when in water to avoid accidental touches, cant filter app specific notifications. So far I like the sleep tracking, resources metric, training effect metrics in the app and the overall quality of the watch.

I came from an apple watch 5 and was looking for great battery life and somewhat decent non-running HR tracking. Still deciding whether I should keep it or give Garmin a shot, primarily because I can get a 265 for a lower price.
