Works great! This theme does not seem to have any annoying surprises. Controls and settings are put where and behave how you would expect them. This is not the average, lame theme concocted in somebody's basement.
This theme does recommend one plugin, Responsive Add Ons, from the same author. I had a hard time figuring out exactly what this plugin did. I apologize for the digression, but I'm glad I dug around as it seems indispensable for SEO savvy website developers. It allows you to add scripts for traffic monitoring, i.e. Google Analytics, and other similar purposes. And, it hints at adding more functionality later on. Plus, it works with or without this theme, which is a perfect segue back to the focus of this review.
Now, onto the problems.
This theme's biggest problem for now is a boring built-in front page which is incompatible with Jetpack's mobile theme. The layout for the included front page is limited to remaining forever boring. You can dress up other areas with imagery to try to compensate. But, if you want to use the front page feature, a prominent white box with wide padding and gray text on the left-half will be an obtrusive part of your site's first impression. Thankfully, you don't have to use this page for your front page. This is especially good to know once you find out that the included front page is incompatible with Jetpack's mobile theme feature.
Although at first this theme seemed loaded with customization options, it turns out to be fairly limited in regard to simple changes important enough to necessitate inclusion with the free version.
First, no color scheme changes: You are stuck with white, a lot of dark gray, and the rare splash of a bright cyan button. I'm sure this limitation can be circumvented through custom CSS. But, this should have been a free feature, at least with 3 or 4 colors to choose from.
Next, a dark, blocky-looking navigation menu: The navigation menu has a certain dark, blocky look that will not be appealing for most websites. It has its place in many designs. But, unless the rest of your website lends itself to the established look, it will be an eyesore.
Those were the only problems I found so far.
In summary, if you intend to have a neutral color scheme, have a fair amount of experience with HTML/CSS coding, or have any experience with creating theme mods (modified versions), this free theme may suit you well enough. For anyone else, the intuitive controls and clean look of this theme will make paying for the pro version very appealing in order to overcome the few shortcomings. If you are still on the fence, I recommend trying out this free version until you are sure the pro version's perks will make it worth the cost.
