D'ont spend money for this. I installed the component unter Joomla 1.7. It didn't work at all. The support helped to fix the problem but know the component does allmost nothing of that one can see on the demo site. Changes to the components parameters have absolutely no effects on its behaviour. Forthermore it cannot be integrated within a menu - as seems like to be on the demo site. ALL THIS FOR 35$! Don't use it!
This is NOT a "COMPONENT" its a "MODULE". It does exactly what it says and demonstrated in our demo page.
