Since it’s so quiet here, let me start :)
The Steam Controller, albeit being discontinued in 2019 is still going strong here.
I like that you can easily replace the two AA batteries and even though the original wifi dongle broke somehow, it is possible to just link it with Bluetooth as well.
The buttons are just too noisy and so is the rumble if you turn it on. Overall I love mine to death and will mourn their loss when they all finally break, but I’ve gotten so much use out of them it’s crazy. I’ve done raids in WoW as MT using Steam Controller as primary input. Did that for years, got fairly decent at CS:S, racing games, even done factory building and that kerbal space launch one. Damn things are so versatile, but definitely showing their age compared to my Steam Deck. It would be nice to have a refreshed Steam Controller.
