It doesn't support hinting, if you use full hinting, download https://fonts.google.com/specimen/Roboto and unzip it to ~/.fonts. Then update font cache: sudo fc-cache -fv
Perfect for any ocassion. Christian Robertson is really good, I had no kerning issues with it and it is overall very professional and well-made. And it's free!
One of the most reader friendly fonts that I know of. I always used it for windows applications and I'm glad that it exists for Linux.
