How often do you change out your buttons/stick?

I’ve had my hrap2 modded with obsf30s and an ls32-01 for about 2-3 years now and it’s seen much play. I think it’s about time for me to switch out for some new buttons/stick since they’re getting a bit worn out( i.e. button doesn’t pop back up as fast anymore).

What about you guys, how often do you change yours?
