I have suffered from a similar experience minus the ethernet. One of my hubs was even falsely labeled Thunderbolt when it was not. ALL of my devices were purchased direct from Amazon.com, no third-party resellers. All of them are dead as of today. I switched to using a USB-C -> DisplayPort cable for video. I upgraded my Macbook Pro, so I actually have a selection of ports. Prior to this I spent hundreds of dollars on so called 'docks'. I will never buy from these companies again. I will also never buy a USB-C dock again. Instead, for my Windows laptop, I have USB-C -> USB cables, and it also works with USB-C to DisplayPort. My Macbook has all the required ports.
