I use 16 GB CF card for my DSLR This is in each case the variants with 90 Mb / sec. The read speed of the card, I can fully exploit with the card reader, I am therefore fully satisfied. A nice gimmick is the folding function of the card reader so the reader can also wonderful carry in your backpack and you do not fear that something gets lost in the card slot. On the underside of the card reader is provided with a very non-slip rubber, he is again on the table, he also no longer slip, so no need to worry that it falls off the table unintentionally.
One problem I have with the device, the card reader was plugged in at startup, so the cards are not plugging recognized. The card reader then has to be deducted only from the USB port and reconnect it to be plugged. This sucks a bit, but as I said, it provides otherwise very good job. From me there is therefore still 5 stars.
