Sirve y mucho, es bastante buena extensión, lo único que hecho en falta es una opción de no deshabilitar para que uno no recaiga en momentos de debilidad y también que no funciona tan bien con pornhub, si tienes el enlace de un vídeo te deja meter aunque sea solo usando el buscador.

Great tool to avoid distraction from reading news etc. while working. Easy configuration, but still very powerful.

Excellent at blocking me from sites that eat up too much of my time. Glad I found it!

This add-on is amazingly configurable and well-organized. I've found it helpful.

This extension has helped me so much. Thank you so much James!

Funciona muy bien!

Awesome!!!

Helped me get back my time on desktop & mobile. Love it

Brilliant. Does what it says. Feature rich. Thanks, devs!

This extension is great at making sure you stay focused. One recommendation to improve the service even more is to possibly allow for an automated pomodorro technique as it is a good method for staying productive.

Really helps me stay on track when I get week in the afternoons.

Great extension can be simple but you can also reallt reconfigure it to the epecifics you need
