If you are looking to add Google Maps to your Joomla website this extension is perfect. It has tons of features and it's super easy to configure. You can literally have it up and running within ten minutes.
I've been using this extension for about a year and a half and it works great.
I'm currently working on a website and I had one very minor, but strange issue, so I contacted Mike and he personal fixed it for me! I also inadvertently caused a conflict once, which was all my fault and Mike helped me fix that as well.
Definitely a great extension!
