I found the button rather...not exactly unreliable but susceptible to some caveats that might temporarily screw up your controls. Not hard to recover but mid-fight it could be disastrous. What I did was turn off the repeater buttons completely and just made a keybind that does the same thing, plus it forces everything OFF on the other windows and such, so if it ever does get messed up I just tap the key twice and it resets everything back to working mode.
