Even though i was a bit scared as they had terms and conditions of no refund in place but once i emailed them asking them questions they were very quick to answer and satisfied i decided to purchase a theme.
Boy it has been a wonderful and full of life experience ever since. The options panel uses Customizer which is pretty easy to use and i use a recommended page builder from them to build my all inner pages.
I consider myself lucky to have found them since i had a few hiccups down the line and each time i posted something in their support forum received a courteous reply the same day evening or very next day morning and they answered them perfectly solving each of my problems each time.
Give them a try and they wont let you down.
