Based on the positive recessions have bought 3 of these charging plug. Big disappointment. Contrary to Bersch frictions the plug does not looks like on the picture, the original (construction) equal or similar, but very different. Is a cheap imitation with other dimensions and the micro-USB connector is so thick that it can not be plugged into a smartphone with shell. The original has a narrow plug in any device fits whether with or without protective covering. Add to that an original for the same price is available. So unfortunately I had to return the goods. Too Bad.
