I do suppose it is not for the average healthy bumpkin. I did not upgrade to ECG yet, I have a handheld monitor instead, I could use it during heart events, also the oxygen sensor would be interesting during some periods. I have no idea why anyone with healthy heart function would need it. But hey, I'm old school, I don't need a watch to tell me I didn't get enough sleep, or how much I got (that is simple math, went to bed at x, woke up at y)Same, if I was looking for a watch I would go with the SE most likely as the ECG gets old after using it couple of times and the blood oxygen is great but I'd wait till the tech is more mature.
