Anker Aluminum USB-C Hub with 4 USB-A 3.0 Ports

SO SAD to have to write this revised review. I've been thrilled with many Anker products over the years, my 'go-to' in this cable type area because all their products I've purchased were good quality and reasonably priced until this one. The real problem with this one was it took so long to narrow it down as the issue. It took being on 2 PCs with the exact same symptoms - critical crashes to black screen appearing to be graphics card related. On the first PC I jumped through hoops trying to solve the issue with countless driver un/reinstallations complete with DDU, moving PCIE slot, removing other hardware attempting process of elimination diagnosis all the time not imagining it was this hub with nothing connected to it and never solving the issue. Jump ahead to moving the hub to a second PC, my server - again with nothing connected to it. Later trying to connect a Bluetooth dongle Windows threw up an 'unrecognized device' error, moved to another USB port - just fine - hmm. Tried to connect Logitech dongle as a test - same error. It took removing the hub, uninstalling USB devices in Device Manager - DISM & SFC /scannow to clean the system up. That was a week or so ago, so I decided to plug this hub back into the USB-C port, nothing connected and this morning the same graphics card appearing issues appeared. Flashing black screens upon booting etc. - it's this hub!
