Does what it says it does on the box. I really like the customizeability, and the delay pages are great for giving me those two minutes to think about if I really want to go somewhere.

It does what it's supposed to do and it does it good!

Useful little plugin that helps keep you on task. It has the awesome feature of being able to set different amounts of time for different groups.

I'm from China and I am always tortured by the " virus catcher" such as 金山毒霸 which colonizes my start page when I turn on my Chrome and Google. I even entered the regedit and tried to fix those browsers, but it never wored. Every time I start a browser the "duba.com" would appear instead of a neat start page with my bookmarks and often-used sites. Then I found this, which could block literally everything like a Mr.Muscle cleans a jammed toilet. It feels UNSTOPPABLE, UNBLIEVEABLE and most of all, like you are having your time of your life. THE best blocker in the world, definitely! If I figure out how to donate this in China I would certainly give hundres ( could you guys open Ali pay or We Chat pay? Or even Google Pay? which I could use to help you guys create another masterpiece like this?)
Anyway, a great add-on

Flexible and easy to setup. I love the delaying feature. It gives time to think about the next important action.

Great tool to back up the decision of focusing more during the workday. Love it!

Amazing app. Helped me block all the distracting websites and makes sure I concentrate on my work.

Tremendously useful addon. Once a week I need a no-distraction session and leechblock helped me in that.
