Best card reader with a USB 3.0 connection

I had the opportunity to four card readers of this type to test (card reader incl. USB 3.0 port)
2x IcyBox IB-865-B (in both the card reader itself was not working, but only the USB connection)
1x CSL All-in-One, Model Number: 21061 (unfortunately this was broken)
1x USB 3.0 Sempre (here was the only card reader USB 2.0 with no evidence daruf)

The most expensive of them all:
1x Akasa AK-ICR-14, for directly without any problems. Everything works as it should, and Windows 7 (64-bit) was immediately recognized.
Thus, full 5 stars.
