I know in the product description it says not to connect this adapter up to other adapters, but I did it anyway. I connected three of these ITANDA USB-C to mini display port adapters to my new touch bar MacBook Pro, each one of them plugging into the official Apple dual link DVI to DisplayPort adapters. Then I connected the Apple USB-C to regular USB adapter, connected a hub to that port and then plugged all of the Apple dual link DVI USB cables into the hub. This allowed me to use three 30" Apple Cinema Displays at 2560x1600 along with the internal laptop display. Note that the USB from the adapters must be hooked up in order for the display to turn on, which might be the problem others are having. Its great except now I need to find a dock with some more ports so I can charge my laptop while using this setup, which will replace my old Mac Pro tower.
