It took them almost a year but I think they fixed many issues.
-The heart rate works ! Not in all situations (weight training or any cardio with too much movement) but more accurate now than before.
-Calory counting is more accurate as well.
-The OS is snappier and not that laggy as in the beginning. Maybe that reduced battery life but this change made it more modern.
-More analytical info is displayed when exercising.
-Sleep tracking is the most accurate of all trackers out there. I hope they maintain it.
-Speaker is louder and now you don't have to increase the loudness of the speaker from the mobile.
Now it's worth it. At launch it was a bit of disaster.
Smartwatch capabilities are not that great but it's a fitness tracker after all.
