I installed this blocker after having some trouble with the older style blocker I had been using for more than a year. It was easy to install and use. When I had a question, the author answered in very quickly and helpfully. I’m now easily able to customize the blocker, and it also allows quickly pausing and resuming if a site requires it. The author put a lot of hard work into creating 1Blocker, and it really shows. I’m using it on both my Mac and my iPhone, and I’m very satisfied.
