Something issues made at the beginning of the synchronization with the message center under iOS. But after a factory reset the clock and an update of the Pebble app now everything is running smoothly and reliably. The operation of both the clock and the app is really self-explanatory.
The clock itself is well made and comfortable to wear. The silent alert can be felt clearly, so that you do not miss notification.
Noteworthy is the really low power consumption. The 5-7 days, which are indicated as battery life, are not exaggerated. It comes with the clock without recharging through the workweek.
I would like to criticize the first not reliable coupling with the message center in iOS and the Proprietary charging cable. The magnetic DC plug is very innovative, but forces you to travel to another cable lug around.
