OK, the battery is like the entire smartphone also a real bone. But do not stört`s.
The first endurance test has also passed with flying colors the device. My one year old daughter has lashed out to me the part at point blank range close attention to the teeth. Lo and behold, no scratches. Neither the phone nor on the teeth. Wow, these outdoor units :-)
Synchronization with Outlook works thanks to an app just as perfectly as the paddocks with my car kit.
Both SIM cards are easily recognized.
I really noticed anything negative, but I am admittedly no one who looks at 24 hours with the device.
In my view, the part is highly recommended.
However, the headset is garbage.
