My old card reader, the card had put () and it needed a new. How did I come to this one? On the one hand I think it looks much better than the normal card reader from with slots for 25 types of cards. The folding mechanism pleases me and I hope for a bit of dust. I am no one who traverses the reader and evaluated the data accordingly. However, he hangs with me even on iMac and MacBook Pro. And in both cases he is doing his service afloat, even if there is no USB 3 port. But it is felt more quickly than with my old card reader. I suspect that the Lexar card reader has a newer controller that makes it possible to achieve a slightly faster data throughput even on USB 2. My conclusion: A little more reasonable reader, I would like to bring me back.
