Great little Chrome extension for web filtering and URL threat detection. Been using it for over a year and I'm at the point where I just trust it every time it blocks a site. So I navigate away and get on with my day. I put it on my kids' Chromebooks, too, because I don't even want to know where they're trying to go but now I don't have to worry about it. I can't believe it's free!

Easy to setup but too many false positives, better to stop using internet.

So far, so good. Easy to set up and to use. The only thing I would change is the ability to have a custom block screen or have blocked sites redirected to a home page or specific page.
