This is a top quality theme. Its powerful and intuitive interface makes designing an attractive, functional and responsive website foolishly easy.
I'm just off to purchase the premium upgrade, which will be money very gladly spent.
A big "thank you" to the development team who've clearly invested many a long hour creating and perfecting this theme and other software - including the invaluable 'page builder' plugin - only to make it all freely available. Fantastic stuff, cheers guys!
