I give this theme and company a 5 star. The support has been very good (summer of 2020) when you use their support ticket system. Here is full transparency of my experience:
Install - a few problems, acknowledged by support and repaired in a couple of days. Not instant support, but it was addressed.
Ease of use - the theme has some strange ways of including into the one-page setup, and it takes a little getting used to. Once (with the help of support) I was able to understand how it all works, it isn't my preferred way of using a theme, but it does work very well.
Content - the demo content is confusing (I have shared this with the support team). A page name, is different than the menu item, and different than the content on that page. So clarifying this to make it consistent will help and speed up install.
Effective performance - the website is performing 100% as it should, after support assisted in cleaning it up.
Yes, my install process was not perfect. I would have given this a 3 or 4 star review at that point. After working with the support team, and their help in understanding, I give it a solid 5 star rating and will work with this group again. I do offer the details of my experience in hope that it does get tidied up a little, it would save a bunch of time.
I recommend it. It's a nice theme.
