Mine works pretty well — have used it with three Intel MacBooks in the past and now currently two different Apple Silicon MacBooks.

One of the Intel MBPs did not like it. Would reboot every time I unplugged it from the dock. I blamed that MacBook for that one, since nothing else was ever a problem. I sent every crash report to Apple, along with some choice words that my $2,500 MacBook should be able to handle connecting to a very commonly owned TB Dock. Eventually they did fix it and it stopped being an issue.

Has ended up one of the more reliable pieces of tech gear in my life, especially given the absolute mad complexity of TB3 behind the scenes.
