Good adapter. Works with Catalina and the new 16" MacBook Pro. I did an iperf3 test with it and I was able to get 980 Mbit/s (as best as possible). The quality of the material is good. The connector fits well. I have the adapter been a month and am having problems now it seems to be handling normal handling and abuse.
