I kept putting of switching from Travis to Circle-CI in one of my open source projects, But when I did get around to it the whole thing went pretty smoothly and easily and I regret not doing it earlier. 1.The builds are much faster now. 2. The configuration has virtually no hacks anymore as I'm using Circle-CI own docker images (including browsers). 3. And the UI/UX is superior as well.
