I have tested nearly twenty extensions, only this one blocked the defined sites and closed their tabs. No need for me to close the blocking acknowledgement, which is another kind of annoyance. It is really block site & focus!

Great! Does just what it promises and keeps me away from distracting sites. But it's too easy to disable it and relapse back into time wasting habits. It would be wonderful if it had a time lock to really keep those irritating sites at bay.

nice but sometimes it does not work

Very good. I do not have to pay for the paid one. Now my grades improved a lot thanks to this extension.

This is stupid, I set it up to block convertio.co but when I try to visit https://www.trustpilot.com/review/convertio.co (which has nothing to do with convertio.co) it blocks it for no reason, get out of here

Great!!! it works

This is useless. I set this up to block a specific page in a website that would mark my messages as read, but the list didn't sync over when I switched to a new computer, so the site opened and my messages were lost. EXTREMELY annoyed.

Simple and effective, no need to pay

Simple and clear
