I would like to share my experience using Highend Theme.
First of all, the theme looks amazing and neat looking. Second, the description stated the theme is RTL ready. So, I started playing with the demo in the official website. As a result, I bought it so I can use it for a small personal blog as a pilot project.
After awhile of working on the theme , it doesn't support RTL 100%. So, I started opening support tickets for things that need to be fixed. However, not all problems were fixed by them. Thus, I started doing their job, fixing problems. To be honest, I am not a web developer, but can understand and modify PHP/HTML/CSS codes.
Currently, I think the theme is not ready for RTL commercial websites where the brand image is so important to the company, unless you hire another developer/designer who fix things on behave of the theme support.
All in all, Highend Theme is not recommended for RTL websites where absolute website perfection is a must to protect the brand image.
