No issues with syncing to iPhone. My charge usually lasts 4 full days. Love how it can charge on any USB, so simple to use.
My steady goals:
work only - 2,500
work + workout - 3,500
work + sports 4,500
Best day: 5,456
Gotta figure out how to get a 10k day...
Got my grey/yellow in the evening yesterday. Fully satisfied. Haven't bought something that looked exactly like the pictures in a while.
Very comfy. Considering going back and grabbing the navy/beige
