Well to be fair, I wouldn't say they're "aggressively marketing" the new sensor. Sure, it's front and center on the Apple Watch page because there's not much else they added this year. They also make perfectly clear that it isn't medical grade.Yes, maybe I should accept that their main feature introduced in Apple Watch 6 is not working for me, because as you say, I don't really need it. Excellent point. However, considering how Apple responded to my problem where they don't care and just leave it to be my problem, and the fact that they are marketing this aggressively, makes me considering returning it. Does that makes sense ?
Everybody's situation is different and I can only imagine the amount of complaints they receive about each and every little thing they include (ECG doesn't work perfectly for a lot of people and this is medical grade). What should they be doing to make you content with their level of "care" for this issue? New watch? In-person troubleshooting to figure out what you (or the watch) could be doing wrong?
As somebody who exercises regularly I would think the fitness tracking capabilities would be your main concern. For me, each time I get one of these watches I see my activity levels increase due to the coaching and goals the watch pushes. It's all very motivating. I can count on one hand how many times I've used the SPO2 sensor and that's mostly been to show people who know I got the new watch. It really is more of a gimmick at this point so I would focus elsewhere to determine the worth of the watch before returning it.
