Going to have to pile on here. The Flex seemed like it was going to be cool, but then the software was buggy for the longest time--wouldn't sync, silent alarms wouldn't work, etc. These are largely fixed but now they won't add HealthKit support. Seems stupid since the software isn't their strong point. But whatever, despite the lock-in attempts I'm not sticking with their stuff. Really like the Flex form factor but can't stand the platform at this point.
