Firstly, this theme does indeed look nice. It's really well-designed. That's why I picked it. Unfortunately, it does not seem to work as well and as simply as one might hope.
Yes, the support does seem to answer quickly but often the support answers are vague or not helpful and require back and forth.
It has taken a LOT of CSS tweaks to get this site looking like one of the demos. The font selection functionality in the theme options doesn't seem to work at all - and that's after deleting and reinstalling the theme.
There's IDs and classes all over the place, seemingly in a somewhat unorganized fashion.
My suggestion for the theme developers is to clean this theme up, ensure the Theme Options actually works, and ensure that the support you provide is really getting to the root of the problem. After all, we pay for these themes.
I probably wouldn't purchase this theme again.
Lastly, I want to reiterate that it is very nicely designed, visually-speaking.
