I manage websites for million dollar research labs (yeah, why they use WordPress with free themes is beyond me). Unfortunately, upgrading to the change that the new company made caused issues for the sites that used this theme. First: The new theme forced it's default home page upon the site even though it wasn't checked. Second: Even though the site was changed to 'use posts', it created a new page entitled "posts" and changed the default to use that static page.
If the company can't check the code & install to ensure that it will not alter the look & feel of the home page, I can't advise clients to purchase the pro option. I would be extremely cautious when dealing with this template. Double check every page when upgrading to ensure nothing is lost.
As a side note, it's really annoying that the theme tells the user that the responsive add on plugin is necessary. The plugin doesn't add a lot of functionality and it isn't necessary. Unfortunately, there was no link to the information about the plugin, just a link to install it. If you're going to put that big warning in front of users the least you could do is link to relevant information.
