What happens when you just download FasteR? Does it work for a limited period and then stop working, will it ask me for a license each time I start it?
Also, why would I pay €399 for FasteR while its main competitor is more mature and completely free? Aside from Excel add-in, the two other reasons I've found are in the comments here: "graphical user interface for selected packages/functions, support for multiple monitors". Am I missing something?
