I have this Nifty Drive ordered for my MacBook Pro Retina 15 "Late 2013, and it fits perfectly. I had already must send back an order of another Nifty Drives, as it in the built-in card reader is not completely into fit and thus a couple of millimeters out stand. Now I found this article, which is perfectly matched to my MacBook and also priced significantly (currently about 10 euro) is cheaper. I would buy the product at any time and can only recommend it.
