I have used it with my MS Surface Pro 7 with Surface Dock 2 and it works well for connecting external monitors and for connecting a USB-A device. However, there is one small issue - a notification that "USB device may need more power" - and a yellow "!" triangle warning above the battery/charging icon in the taskbar. I don't think there's any real issue in the end, other than the lack of pass-through power (for fast charging) for the USB-A port, but it still annoys me to see it. Apart from this small problem, the device worked perfectly.
