to add on the other review if you dont like it your stuck! Be careful of no refund policy or trial period....in my experince never seen software sold as like, dont like it , no trial your stuck....buy at your own risk!
However as is chronically a problem in the Joomla community the documentation does not exist to setup and configure the plugin. Instead be prepared to invest HOURS of your time decoding any RSJoomla products. They are very good, but their help and support is as complete as the documentation.
