Not all of their maps are included in the free version and the only way to find out what’s included is to install the plugin and check.

I installed the plugin thinking that I would be able to use it for clickable US state maps. It turned out that option was available…in the premium version only. The free version only allows clickable US Regions.

I don’t mind paying for plugins, but it would have been nice to know ahead of time so I could make an informed decision.
