Love my Amazfit watch. It is a very underrated watch. It works better than my Garmin for most things and keep their charge for almost a month.
Only 2 years ago Amazfit had no update policy whatsoever and a new model of your watch pretty much meant no more updates for your watch. Now they are committing to 3 years of regular updates on all new models and have shown over the last 2 years they are serious about it. This is more than most other wearable brands, save Samsung and Google, but Amazfit users have nothing to complain about and I hope to rejoin them when the Balance 2 launches in Europe.
