This is my most important productivity extension, and I have used quite a few.

really really good, just wish it had an option to stop overdrives ha ha

Superb, life saving extension. An absolute necessity.

I love this app. It keeps distractions away during work hours

Very useful and convenient to use. I love that we can block the sites during specific times as well as put a time limit at times when the sites are available , also love the option to prevent editing the time block when blocking is active

it works well!

Very good, very helpful. But as some other users mentioned; not the most user friendly

It's very good, but its not very user friendly. However the leech block forums are very helpful to figure out how to find your solution.
