Good but it does slow down page speeds considerably.

It surely has pretty design and smoothly darkens most of common sites BUT it slows down page loading for even MINUTES. Firefox 61.0, wire connection, works with speed-of-light without add-on.

It creates aesthetically better pages then any other extension and works excellent on most sites. However, as others mentioned, it indeed slow page loading (sometimes significantly)

I experimented with a few different "dark mode" extensions and this one gives the nicest result.

Nicely helpful for shading pages and helping to reduce eyestrain.
Thank you,

Thanks for this add-on, I can't browse without it! I love to be able to swith it easily between light and dark !

Muy bonito y funciona en la mayoría de páginas.

so far I really love the app

Es muy bueno, pero comúnmente ralentiza las búsquedas y genera problemas de compatibilidad con ciertas paginas, por ejemplo Gmail.

Bonne extension. Je confirme, c'est plus agréable la nuit. Merci au dev.

Good

Does a great job of styling, but at the cost of page-load speed. Pretty sluggish performance while using this add-on.

Unbeatable, tried man and always found a bug or something not working correctly. Dark Reader nailed it!
