TouchID was working fine >80% of the times on my iPhone 5S. After some updates, it worked something like 95% of the times.
With the iPhone 6 I still have to see it fail once....
Absolutely happy about it.

Brother's phone been perfect since launch day.
Mother's phone touch ID starting to fail I tried a full factory DFU restore too it just doesn't seen to read finger print as well.
My phone been great from launch day but the front face camera somehow moved out of place I really don't know how did this happen.
