On the plus side it looks very nice, and like the options you have, if only they worked.
Support is very good, with excellent documentation which is rare in the Joomla extension world. All options are explained very well in the documentation, and makes this very easy to set up.
The software itself works as you would expect it to, and is very powerful.
The documentation is okay, and the support is good, although it was a little over my head, but got me headed in the right direction.
