These controllers were all working on SteamOS before as far as I know, so I’m interested to see what this changes. My understanding is that previously their controllers just show up as generic xbox controllers, and now they will be properly recognized. We’ll see if this has any other benefits like custom bindings for back buttons and things like that.
Upside, usually the controllers are extremely easy to fix. I’m not sure if they give free replacement pads still, but they used to if you asked support.
I’ve had other problems than shoulders on my pros, and never with the ultimate one I got, those seem to have a pretty solid build.
