I tested this card reader with a CF card and two SD cards. Transmission speed is good. Addendum: I've been using this card reader for a few weeks now. I had to change my rating from the original 5 stars to 3 stars because the card reader might turn off accidentally. Sometimes the connection gets lost shortly after connecting. Sometimes it seems longer. If the connection drops, I have to unplug it and then plug it back in. Second Tracking After the previous tracking, Saicoo offered to send me another example of this card reader for testing. I've been using the new card reader for about two weeks now on Windows and MAC computers and the new card reader works reliably. I think this card reader deserves 5 stars.
