love the way this watch looks,   unfortunately as per my personal problem - the lack of 3rd-party application support.   eg. does not support feeding information to "sleep as android" or any other "alarm app" that might take advantage of continuous hr and sleep monitoring, and given the weak vibration motor inside, it does not have the strength to wake up a heavy sleeper.    other than the minor subjective/personal objection, this is perfect:  - great look  - wide "smartwatch" functionality  - comfortable/ergonomic wear  - decent 3-5 days battery (depends on the vibration strength that can be configured in settings)
