Facile et efficace

It's amazing. I use it on both my computer and my phone. Thank you so much. It help me a lot.

非常好用。

It works, and has some extra features (every time I try to open YouTube, I get directed to "Shouldn't you be studying?" with David Tennant).

Truly block the unwanted sites. Nice one. A redirect option to custom website may be more helpful. Thanks!
