Great eyesaver. Sometimes it makes websites unreadable (ie light text on light background) or just ugly but I doubt you could automate this kind of thing perfectly, and it's impressive how well it creates dark themes considering it's not done by a human. And if it does make a website ugly or unreadable you can easily disable it for that particular website, very hassle-free.

Works great! I'm a technical creampuff, but this is easy to use & is among my top 3 favorite add-on extensions. Recommended!

This is the bomb-diggedy! I love how easy it is to use and that there are keys to toggle between light and dark!

Very good I love it
