No pb, everything is my perfect taste. The number of buttons is adequate, and the sticks are neither too sensitive nor too blocker. The arrow keys allow a very good action with pre diagonal arrows dessinnés because the button is surelevé thereby supporting diagonally eg DO without pressing simultaneously on those N and E (up + right)
There is also a back button that lets you toggle input direct mode and X input, very nice! And handling, grip, is also very nice.
No problems and very satisfied. Also pleasantly surprised for the price because quality and ample functions, what else?
