Ps3 controllers suck

I’ve broke like 6 controllers.. I was playing some MW2, and my analog stick broke on me! Just normal playing and it’s not even a months old i don’t think. My mom & dad are goin to be pissed. So i took it apart to trying and fix it, and the damn thing fell apart! The R1 buttons and all that fell out, and i can’t eve get them back in. Why can’t they make a simple controller that is easy to fix.
