I use the Reader for reading images in RAW format, and sometimes even parallel of JPG images. Individually, logically super fast reading through USB 3.0, but also good at simultaneous charging of both slot's. I have a device from SanDisk, which is this in any comparison. Double as fast as I would not say, but I think there are perceived 33% (one-third) faster than the part of SanDisk. What is already not negligible at large and many pictures. SD card slot as well as the inclusion of CF are robust and even put in a ruppiges bend any contacts.
I am very pleased and would set me the part again.
