I have been using Kordex for a few months now and I really enjoy it. This is my second experience with WordPress after a first website built in 2014.
I really appreciate the flexibility provided by Elementor and the various options of the theme. However I would not recommend it for beginners.
Documentation could be a bit more detailed, in particular when it comes to parameters, default values ...
The level of support is outstanding and would deserve 6 stars. Very reactive, always ready to provide help with css, make changes to the theme when needed. I am currently translating the theme using WPML and the team support has been incredible. This is my first experience with WPML and I would not have succeeded otherwise.
