I needed a very fast card reader to download my photos. This drive fulfills this function, I put a 6 min 30 to empty a 16GB card of raw and jpeg files from my Canon 7D. I was connected to an express card USB3, my PC does not have a native USB3 socket. Tested USB2, it puts a little less than 12 minutes for the same work. I tested it with Lexar 1000x card. The presentation and finish are good player. The ability to close the to transport and to avoid dust is nice but the owner is difficult to cable and remove. This still limits the mobile use. This player plays all CF and SD cards, even UDMA7, other readers offer other formats including memory sticks and XD but I do not have to use. Overall happy with my purchase.
