I think the fact is this theme is free and so easy to handle it is awesome! I think gozalbes is kind of right tho - till a certain point. :) . I had to do quite a bit of research till I got right how to actually build the site. Since then...its easy as pie!
Great theme, thanks for the makers!
I messed about with several Themes before settling on Advantage.
It leaves a lot of the other Themes dead in the water.
It's easy to grapple with, you don't have to mess about making 'Child' Themes to get it to do what you want it to do.
Next in line, though is Polaris, from the same stable, and it is definitely a Theme to look out for in 2014
Demo screenshot hard to reproduce.
Lack of documentation to obtain a layout like demo.
The feature that sold me on this theme was the responsive slider. While it doesn't have a huge array of options by default for the slider, with a small bit of tweaking I was able to get this doing exactly what I wanted. The theme is clean and well-programmed, and it is a great platform to do what you want.
Far too many themes try to do too much, and become a sort of jack-of-all-trades-but-master-of-none. This does what it does, and it does it extremely well with the responsive coding working perfectly for me. The simplicity means that I can take it and do what I want with it. Great stuff.
