While it blocks wonderfully it also slows down the browser to a crawl. Using it on Facebook is hopeless.

Also it does not allow for case sensitive keywords, that means that blocking "GoT" which is an essential phrase at the moment, also blocks "got" which is such a common word that half the Internet is censored.

I like the look and feel, and it's easy to understand what's being blocked without spoiling in the process.
The ability to whitelist pages helps a lot.
