The most important part of a dock is the type of ports it adds to your current setup. While the Mac mini M4 in its default state is good, it can always be a little better with just a few additional ports. This dock adds a good mix of ports with one USB-C and a 3.5mm audio jack, along with an SD card and microSD card reader on the front. On the rear, you get DisplayPort, two USB-C ports, one USB-C port, and a 3.5mm audio jack. The great part about the Ugreen dock is that it's extremely well-built and has a great design that makes it look like it's part of the original hardware. Just make sure t
