Customer support is fantastic, however having being on here for around 10 years, and using many other themes the CWS builder is very restricted and confusing. If you are used to using JS Composer, then you may struggle at first.
I bought this theme despite having the wordpress files already just to give them the money they deserved. And when I encountered a few issues with customization, their Customer Support was so efficient and lightening fast! They resolved all my issues within half an hour! Great people and Great theme!
