This is an excellent theme right out of the box, with a lot of options for making minor tweaks without having to getting into a lot of complex coding.
What makes it great is that the developer is exceptionally responsive and helpful. He's helped me solve a number of issues and incorporated the fix to one as a new option in a subsequent release.
One thing to be aware of is that this is an HTML5 theme and as such contains some elements that older browsers (e.g., IE 8 and earlier) may not know how to deal with. You can address some of those by adding the Modernizr plugin or something similar, but certain elements may not translate. This is in no way an aspersion on the theme -- just something to keep in mind, especially if you're developing a site for a client.
