Works as advertised
Have had no problem using this reader on either my MacBook, iMac or Windows computers. Not the most compact reader, but still small enough to keep in my laptop bag. Nice that they include cables to connect to USB-C and USB-A type connectors, so basically works with every computer.
I just tried this with my iPad Pro and it imports CF and XD cards very fast and reliably. The build quality is excellent. The Length of the USB cables are just right for my portable field use situation and even long enough for most desktop computer with front USB ports.
Transfers through this card reader into the Thunderbolt 3 port of my MacBook Pro are screaming fast. While shopping for devices for my new Mac, I learned that the USB nomenclature is incredibly (deliberately?) confusing. This card reader is genuinely USB 3.1 Gen 2. Its that Gen 2 that makes all the difference in speed (twice as fast as Gen 1).
