I had no problems with this as it was used with two different MacBook Pros (2016 13" Touch Bar and 2018 13" Touch Bar). I've tested it in multiple locations from gigabit ethernet to 25Mbps and have had no issues with the speeds, reading and testing at the full speed available at all times. Literally just plug and play; Plug it in, plug in ethernet, plug in the wall and it works. I can't ask for more as the prices were fair too.
