Unfortunately deficient. Although I am a good customer and the Amazon also probably continue, but this cable is for "Katz" probably better than for my Retina Ipad. Bought in May this year, it has held up well until about August, unless it is slipped out, since fixed it never was in the Ipad. Often noticed that it just slipped out during charging ... Well, but from about August onwards, came the bad contact and went in October then do nothing more. I thought my iPad would have a problem, but now works with an original Apple cable from the Apple Store again everything 100% :)
