Only me is one noticed: if you get on the iPhone / iPad an error message that the product is not Apple-Certified, just try a different power source / battery charger. According to dealers, it is then not the cable but at an inadequate power supply (usually cheap power supply units). I could adjust it: Samsung charging cable = error, the original Apple charging cable = no problem
*** UPDATE *** after 5 months
Use the cable for about 5 months daily at my iPhone 5 to load in the office! No Problem. Impeccable.
