Very nice single page theme, with prompt support
My issues were with the spacing of the Title and Header, and with small tweaks to the css it looked great. When I couldn't get the mobile version to look right, jb1 was very responsive and released a new version within a couple days.
This theme is well thought out, and well supported. I now have several clients using it and they are happy and the sites are stable and attractive.
Excellent Black theme
I didn't need to contact the author for this theme but I have asked for support in the past, that support is as good as this theme, five star.
Great theme - C5Extras are the best
The theme is really nice. It takes a little bit of getting used to and it helps to know a little CSS if you want any changes, but it really is well thought out. My only issue was I wanted a blog on mine, and in the example there is a blog section. It wasn't really working as I wanted at first but jb1 added some new page types for me and now I have tweaked it to work for me.
Single page layout is a special way to have a website. Very Modern, but limiting. As long as you are aware of that, then go ahead and buy this theme
