Five-star for good customer support. They have the ability to resolve any issue in less than the time for a coffee cup.
This has already been my fifth-time purchasing their theme. I have been highly satisfied with their work every time.
There's nothing would satisfy me much more than a worry-free clean and responsive theme for my high-traffic site.
I can say your dedication is second to none. I like the fact that you are strongly proud of your work in every way.
