I bought two cables and now with both I make a pretty disappointing experience.
Positives:
The charge current is very stable up to 2 A and loads as well as the original cable. The workmanship is very good and everything makes a very high-quality first impression.
The vulnerability can be seen only after several weeks use the material for the mini USB ports is weak and flexes after a certain time. This is the cable gradually unusable because the connection to the receiver bushing always loose and wobbly.
I've tried in the past year a number of cables in different price ranges. This was so far the best but still with a very limited life.
So you can effortlessly in 50 or more to spend on Ersatzkabbeln because they either did not even invite properly or if then very early to give up the ghost.
