It keeps the promise of the ThinkPad brand.
Lenovo is succeeding to keep the quality of the ThinkPad brand. The adapter works perfectly with all OS supported, included Linux, tested with Debian, Red Hat and Intel Clear Linux. Online shop and logistic perfect. Reasonable price for the quality delivered.

ThinkPad USB3.0 to Ethernet Adaptor
I bought the ThinkPad USB 3.0 Ethernet Adapter to use with my 7th Gen Lenovo Carbon X1.
As I have two USB C cables plugged in the included special dongle does not fit well if a USB C cable is plugged in next to it. This adapter solves the problem. It works straight away with no fuss.
