It works just as it intends to. Adding ethernet to modern work laptops that only have wifi while enough USB slots for a mouse, keyboard and usb head set. The fact that is has USB type A and C means it will work with any laptop configuration. This unit is just handy to keep in the draw if needed too as its small and nothing else is required. I would recommend this over a 4 port USB as I see ethernet ports moving more and more to a USB C or A adapter.
