Having been involved in WordPress site building for a while now I have purchased various themes and plugins over the years. Whenever I have had a problem customer support has ranged from acceptable to virtually non existent.
Recently I had an issue with a Theme and posted a support request, the post was responded to within an hour or so and after additional information from me was posted the support agent logged in to my site and corrected the problem. All in the same day!
Look no further if you need a great Theme with awesome backup!
