I’d give it an A+ for costs, and an A for features and an A- for accuracy. All in all well worth the buy and I really like the PAI, HB, Training Status, Blood oxygen, phone features and workout history features. Still trying to understand the sleep monitor system and the altitude monitor is not consistent or accurate. Had it for about a month and very pleased so far.
I really like this watch. I thought it might feel bulkier than my old Band 7, but quite the opposite, it's really comfortable and feels lighter than I expected. It does a much better job tracking my sleep, including awake time (reading in bed middle of night) which the Band 7 didn't detect. The GPS is surprisingly accurate (even when I don't bring my phone) and downloading a local area map is quite easy. The auto-brightness is so welcome after the Band 7 (manual brightness only) which would be like turning on a flashlight at night and would sometimes activate when it shouldn't - but the Active 2 has none of those issues, in part i think because it has buttons to manually active during "sleep" hours when wrist-flick and/or always-on are disabled. Anyway, I would definitely buy it again.
Haven't wirn a watch for a years and years. I like having the time available on my wrist again and having considerably more information available to me. I do not use some of the features yet. I am still learning about them. I like the watch very much so far.
I'm very impressed with the watch. I receive more important health data on this compared to others. I've just noticed it comes in very low in the area of calories burned compared to other devices.
