Review on Dell WD15 Dock 4K with 180W Adapter, USB-C, (Model: 450-AEUO, 7FJ4J, 4W2HW), Black, Dual Display by Jon Bishop

To be honest I don't understand why everyone has so many problems with this docking station. It comes with a very clear instruction stating that you must update your computer's BIOS before using it. Just go to the Dell website and download the BIOS update as well as the wd15 firmware update utility driver and Realtek USB audio driver. After installing these 3, this thing works exactly as advertised. I use it to connect 2 external hard drives, USB receiver for wireless mouse and keyboard, headphones and 2 monitors. It worked flawlessly for the month I was using it and to my surprise it also charges my Dell XPS 15 which powers everything else plugged into it. I can't be the only person to get a working device, just follow the instructions and you'll be fine.
