Appears great with iPhone. Much info, the story is very well featured in the iPhone app. Sleeping function - Easy sleep from the phone is still standing, it seems like deep sleep, I do not know it is well presented and can indicate reasonably. When over two hours of deep sleep is indicated, it feels like I've slept better than when it's smaller. The battery lasts very long. The display is very small and it is difficult to read the time. The pulse is read rarely, unless you ask for it.
The bracelet draws the grade with two stars. Suddenly the band was no longer on my arm, looking for it outside my home or at my workplace, etc. to connect Bluetooth that starts vibration, gave nothing anywhere. The band has been unloaded twice, and you have to simply arrange something for it to remain. I'm trying to figure out how.
When I lost the tape first, I obtained a Denver BFA-15. I've had it next to my later found xiaomi 2 and compared, and xiaomi mi band 2 is clearly better.
