I've got a launch-week Quest, which uses the exact same Touch V2 controllers as the Rift S, and i've been slamming the shit out of my controllers with no issue so far. I've punched the wall, my PC, my speakers, my sofa, my dog, some shelves, some shit on the shelves, myself, the ceiling. If it's in the room i've fucking punched it with my touch controllers. And they're as good as the day I got them.
