Bests & Worsts Reviews from Amazon

Display font is too small and there is a bug in changing the watchface that limits your ability to make changes. If they can fix these items I'll increase my rating to a 5 because for the price it has more functionality than the Fitbit charge 2 hr, which I've used for the last three years at 3x the cost. FYI, I've got 20/20 vision but am 44 and my vision is not great for the first 10 minutes when I wake up. During that time there watchface is unreadable. Otherwise there are screens where the font is like a 2 or 3, and still difficult for me. This is a major oversight that since very minutes user testing would have uncovered. Too bad because it will generate lots of negative reviews on Amazon. Update downgrade to one: sleep data stopped tracking after three days. PAI is worthless. The Zepp app is obviously not ready for prime time. Do not buy.
