Review on Tiergrade 8 in 1 USB C Hub: 4K HDMI, Power Delivery, SD TF Card Reader, USB C Port + More for MacBook & Type C Devices by Daniel Greene

Hub received today and so far so good. works as it should. For USB-C ports; 1 is used for passthrough charging of the notebook, but data transfer does not work. However, you can use the USB-C wireless charging port to connect an additional USB-C device, as I'm sure that's important. Overall I am satisfied with the purchase. There is an opportunity to register on their website to extend the warranty for another 6 months, but they had a clear way to register the product (provided by creating an account, but nothing happened after registering). You can also go via FaceBook but aren't a big fan of FaceBook so can't comment on the experience there.
