I chose this dongle dock because of the added functionality if provides my 2020 MacBook Pro 13" i7 with 4 Thunderbolt (USB-C) ports. I'll assume all ports work until they test otherwise. iPhone is charging off the USB3 port on a Lightening cable and a Logitech USB keyboard is functioning on the USB2 port. The dongle is made of metal and has good build quality. The dongle just arrived an hour ago so I'll update this review after I have working experience.
