The product is interesting because complete with a generous connectivity. But the internal wiring is deplorable ... After being connected to the motherboard, a USB3 ports do not work as well as memory card connectors ... I dismounted and surprise, the son are not connected !!! (2/4 and 1/9 for memory cards for one of USB3 ... I soldered the missing links (must have already been done ...) and it is repaired In short, nonexistent quality control ... In the end, it works very well but I do not think you want to buy a failed trick and duty repair ... With a little luck maybe everything will work for you!
