I have bought this module the other day. It does the job out of the box. However at the beginning I had one issue and two customization requests. Their support department answered my request at the same day. Two hours later everything was done. Perfect.
This plugin is really great and so is its developer. The plugin worked out of the box with Firefox and some others but IE did not display my map. I tried to solve this for hours, then I wrote an SOS-email to the developer. He shared his knowledge asap and solved that problem. Thank you very much. Great plugin and support.
I am more than satisfied with that module. It works fine without any trouble (tested in IE 6/7, Firefox 2.0, Safari). The fast and helpful support on every question really impressed me and is not usual. Thank you for that!
