This cable was purchased to charge the phone using a mobile battery.
The housing of the cable is robust and promises a long life, the cable itself looks a bit thin. This is, however, due to the need for the retract function flexibility, comprehensible. Both plug, especially the micro-USB end, have a tight fit, but this is for mobile applications more than positive.
Another very useful feature: The cable must not be completely pulled out to lock. It snaps in 6 different lengths. So dangles no excess length around.
Conclusion: As long as you reasonably carefully handle the cable, make it ideally suited for mobile use. Space-saving, well thought out, well made.
Note: Contrary to other reviews can be connected to the PC for data link cable with this smartphone.
