Very reliable. At faster than conventional USB2.0 Readers

Speed ​​/ function
The reader is operated mainly at the USB 3.0 port of a notebook and here so far exclusively for SD cards (SD and SDHC, Class10). The speeds with USB 3.0 not quite match my expectations, but can also on interaction (Dell) notebook and the driver software are used (in this case problems of USB 3.0 connection, especially in Dell notebooks are described in various forums).
On the positive side however, I noticed that the reader of USB 2.0 ports measurable significantly higher speeds (up to 25%) achieved than conventional USB 2.0 readers.

Processing / Optics / Design / Cable
The card reader is small and thus on the desk rather inconspicuous. Why a reader in piano black finish designed to be does not need to completely open up to me. But good that is personal taste. Overall, the material quality and design makes nevertheless a very trusted and solid impression. The connecting cable is USB 3.0 typically somewhat stiffer. With 58cm length, it is absolutely adequate for my needs, but might be difficult for one or the other too short.

Conclusion
In my view, a very good and inexpensive USB 3.0 card reader. I recommend the product you.
