This is not original Apple adapter but a replica, even though I have ordered from Amazon itself. The packaging looks the original confusingly similar. When adapter itself can but notice at first glance differences in quality. I have in fact already such an adapter which was purchased from the Apple Online Store. This adapter Amazon processing is catastrophic or is it to other materials. I have not tested it myself approached Amazon with a request to exchange the function.
ADDENDUM: Amazon has unhesitatingly given me a new adapter, this time an original Apple. So I correct my rating of 1 to 5 stars because of the price of about 12 is comparatively low.
