Easy admin control of almost any parameter that is available. The support, even for the free version of Hika, is first class. The updates are always improving the component and it's extensions and from the very beginning we started it on Joomla!™ 3. Great work Hika team!
The component was installed, bug free, on Joomla! 3.0.1 although the available modules were not yet compatible (as of Oct 2012) with this version of the platform, but minor fixes in code, allow them to work perfectly. The component is well coded and meeting Joomla! coding guidelines and if templating is necessary, it's just sweet to browse the markup and adapt to one's needs, but "out of the box" it just renders beautifully.
In summary, if someone is looking for a shopping component that is hassle free and doesn't make you waste time to configure it, this is my suggestion - really give JoomShopping a try and I believe you'll be as positively surprised as I was.
Congrats to the JoomShopping dev team!
Some of the clients are now willing to purchase the Enterprise version of this component. Great component, great job and great continuous development team.
