It does what it says. It has a nice feature to have more than one pin. It has different style of map. It can't track routes.
The UI may grow a lot. IMPORTANT: The long and lat follow the English decimal notation (.) if you use comma (,) it won't work the module.
I don't know I haven't used it.
The documentation is very poor.
It works out of the box, easy to customize, nice and simple.
