The free module worked fine for us... the only problem we had was that the main features we needed were only in the pro version, so we have moved on to that.

We did ask for a plugin for this, and the Theme Joomla team helped us get that sorted out, so service was good to!

We have been using this extension for a few commercial sites after evaluating the free module version, and the pro version here is perfect for us.

We had initial setup issues, but that landed up being permissions and server setting issues, which were resolved with our ISP.

Does what it says, plus the extension is quite active, and constantly being updated with new features.
