Review on 🔌 UGREEN USB C Hub 9 in 1: Multiport Adapter Dock with 4K HDMI, VGA, Gigabit Ethernet, PD Charging, 3 USB 3.0, SD Card Reader - Compatible for MacBook Pro Air 2020 2019 2018, Dell XPS by Andrew Grimes

I connected this to my Macbook Air running Big Sur with an ethernet connection and a VGA connection, sometimes using the USB ports. In general, the adapter works fine: the Ethernet connection is stable, but the only problem is the VGA connection. After the computer goes to sleep, it is often not possible to wake it up and turn on the external monitor by clicking the keyboard or mouse. I have to disconnect and reconnect the adapter almost every time. Otherwise the device appears to work as advertised.
