Only care about making you upgrade to the premium version.
You don't even get a chance to do anything with the free version to really see if this plugin is what you're after.
Free version only lets you create one map with one default marker. You can't do anything else at all in it.
All wrong from the developers. Should give us a taste of what this plugin can benefit to our sites. It fails to do that and subsequently will lose a lot of potential upgrades to their pro version.
