I've had three video calls with this app so far. 2 were flawless, the 3rd had issues but I think it was because of computer issues the other person was having.
I love the personal branding part of this program, the calendar integration and the booking options (though I haven't used that piece yet). Since so much of my work is doing consultations with clients, this app is going to be a great addition to my toolkit. And I will say that it's be VERY easy to start using - which is not something I can say about all programs. It's actually way faster and easier to use than Skype and it doesn't gum up my computer like Sykpe does. . Considering getting the upgrade as well. I like the bonus features listed but there's a little something extra I know I'm wanting to put it over the edge.
