At some point I had read an article about a so-called Nifty Drive and eagerly expects Apple this in Germany offer-despite an enormously high price. Now I have discovered this product and rummaging it ordered for the MacBook Pro Retina immediately. Unpacking - micro card (s) pure - plugged slot and the USB connector into the SD and everything works perfectly. Bin extraordinarily happy with it. But why only 4 stars? - Because I still wanted something to which, however, is missing: Mac Book Pro has only 2 USB ports. If I need to, or otherwise whatsoever, I must move clear of the USB slot (or the SD card slot). Yes, and then what? Where can I pick up the two parts? It would be desirable to supplement even a possibility of storage offer (similar to the boxes in which the SD card is kept).
