This adapter easily replaces the adapter proposed by Apple. The packaging is pretty close: a beautiful transparent envelope with a black label, it looks very similar to Apple packaging. The adapter is a little late, much wider and a little longer than the Apple model. The cable seems a less flexible hair too, but perhaps this is because it is new. The plastic of the casing is also more matte and rougher than the official. But it does the job perfectly. I tested it with a 27 "iMac and a Samsung 1080p display and it works perfectly. The "problems" of aestheticisms, so that the box is wider is a concern for you, quickly disappear because everything is hidden behind the screen. So great product at a competitive price, 50% less than the product with apple and guaranteed 5 years.
