I love it. It is really simple to use but provides room for you to get as specific as you want using regular expressions. It doesn't add unneeded garbage that you were not looking for. It's super light-weight and won't interrupt your experience or make your youtube tab crash.
I've been using it to block clickbait channels from populating my recommended section, haven't seen the words Mojo or Buzzfeed in a while and couldn't be happier about it.
