Works well. Plug a little hard to plug into the tablet (but at least it sits well!). The key type of storage device usb 16GB march but not fat32 to ntfs. It would have been nice to know at the outset what type of device is suitable for this tablet to purchase the appropriate adapter (if there are any compatibility problems or limit). Indeed, my external hard drive is not recognized. I do not know if this is the tablet that is limited or cable. Yet it is significant to directly connect an external HDD rather than using a PC to do the transfer. So a mixed picture but I would tend to say that the cable is OK and that the tablet that is limiting.
