When I got the 30 day demo license for the Pro version, this entitled me to full support ‘as would have also been the case with a full unlimited licence. And I found I needed it almost right away.
Robert (the developer) gave simply amazing support – he was always prompt to respond, and when we discovered some plugin incompatibilities, he immediately updated the plugin to address them.
I love this plugin, and have not found any others out there that can come even close to Maps Marker Pro.
I highly recommend it!
