Apple to replace a cable ... for 2 months :-(

Apple cables are fragile at the tip Lightning. This cable seems much more robust and cheaper!
(Supplement after two months) ...
unfortunately bought two cables (one white and one black), white tip of the lightning broke away broke away from the white plastic envelope after less than two months :-(

For now I do not have that problem with the black, but I do not know if it was due to a defect in the white or white that was much manipulated by my children and that this type of cable n ' will not stand. At least one cable Apple lasts more than a year ...
