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.
Got one and missed the opportunity to buy 3 more of those.
Only Thing (which made it even more a BIFL Was swappijg the Analog Cap with a Metal Cap for the Xbox.
Looks charming with the silver Analog and is still going strong as my every day gamepad :)
