The user interface is very easy to use, it's well adapted for all users (from entry level up to expert). It has many useful features such as route planning, optimization calculations etc., which makes this software quite versatile tool when you need several functions at once. Some minor issues (like compatibility with older computers), but nothing serious I can think about now. You should definitely give it a try! We are solving problems that we previously did not know how to solve using other systems or tools.
