Beautiful interface, good service
I needed imo because my chromebook doesnt support skype. Now i like it better than skype. Its design is minimalist in the best way and the video quality is really good. When I had a problem a really nice girl from their customer support chatted with me about it and solved it in a couple of hours. And the notifications are way better than the ones from google hangouts.
