I am more than 3 years a happy Raxo customer. I have used this module at so many websites in so many different ways.
The team in Raxo is focused to produce a polished product and they are thoroughly planning each and every new feature in order to keep their top quality.
Briefly the module can be configured to work as a popular, newest, featured, most rated and many more different modules types, with so many further arrangements and settings, like categories and date filtering and so on.
All of the above settings can be done in the module's instinctive backend configuration panel.
However the real power of the module is the templating capability.
Raxo comes prepackaged with some templates, extra templates can be purchased separately, but it also supports custom templates which can be produced with ease by customizing the template php/html code and the css.
Of course the aforementioned knowledge at some level is required.
But for beginners, the ready-made templates can be proved enough and the support is always there to guide them to the right direction or to solve issues.
And the next good news is that Raxo team recently released a new K2 compatible version - listed also in JED.
