There is nothing to give the extension and it's developer Cristi other than the utmost praise.
From my initial contact with him, asking the most rudimentary of questions, through the installation and implementation the process was everything you would expect and hope for from a commercial extension.
It works as advertised with an intuitive interface and well-written guide.
Support is second-to-none. Cristi was there every step of the way with help as well as offering thoughtful advice leading to a flawless implementation.
I support Cristi and all his endeavors fully and will look to him first when it comes to my mapping needs.
