For mobile phones (Samsung i550) my wife and me I've ever bought an original charging cable and had promised me it that it is always better to have an original ... not so at the Samsung CAD300S charger, which first was immediately broken ( a coil had come loose from the board), the second had broken the same after a few weeks. The first cable I still complained and it was replaced without hesitation, in the second I did not feel like the cable and have it by a favorable compatible cable Replace ... with which I am fully satisfied now!
