After buying and trying some architecture themes, I was convinced to try this one. Let's say that this is one of the best, if not the best: it's fast, efficient, easy to use, the general settings are easy to change and quite flexible, there are many templates for pages, articles, images, etc...
I bought this theme with the proposal to build a site in different languages and I realized the enormous difficulty of the thing, to do this I needed a dedicated plug-in that is compatible with the theme even if in a few occasions problems and conflicts arise or settings not so flexible don't help much: for example the Eated image with text are not translatable, URLs with anchor links are not translatable, for them I need a knowledge of programming or alternativelly I had to translate them manually.
Let's say that all in all the theme works pretty well, there are some little problems and sometimes some settings are not very flexible, like for example heights for title fonts with H1, H2, H3, H4, H5, H6 and paragraph tags can't be set, to change them one has to insert CSS codes, color and a style for the border in photos can't be set, the last theme update generated some problems and it was promptly solved by a new update version in the next few days.
All in all, these are minor issues that can be time consuming but I believe they will be fixed in the future by the theme editor.
Also, the customer support is fantastic! They always respond quickly in a short time and fully answer my questions even if sometimes it is necessary to rephrase the question if the assitance gives a generic or not very useful answer, in any case, apart from a few episodes, the assistance is very good and efficient!
