Review on 📸 Rocketek USB 3.0 XQD/SD Card Reader - Dual Slot Memory Card Reader with 5Gbps Super Speed - Compatible with Sony G/M Series, Lexar 2933x/1400x USB Mark XQD Card - Supports SD/SDHC Cards - for Windows/Mac OS by Carlos Nolan

Using the USB 3 port when I try to copy files to my computer through this device, it stops after a few GB and garbles the write to the PC and does not work. When I switch to port 2, it doesn't seem to crash when copying data, but the speed is slow. I know it's most likely not my XQD card's fault as it's a good Sony and seems to be holding up great in my 4k camera. I'd say if you're using this for photography the read errors are a little less annoying as you can just try again from the faulty file, but for large files/videos that's nonsense.
