The SST programming software is beginning to get used to, I myself took about an hour to try until I got to walk all the way I wanted. If you have incorporated themselves ists no longer a problem.
It has three modes to switch (top left) Blue (free), red (role playing), Green (Shooter) are preset, but can be changed belibig using the supplied software. So is for all type of software used (Shooter, Strategy and Role Playing, Office applications, ....)
The 40 Euro are fully OK.
