I purchased mine for full price too. Unfortunately I do not like it for various reasons. Missing dpad and second stick, and holding it is a bit uncomfortable to my hands. And at the early days Steam Input wasn’t this refined. But I loved using it to play with gyro controls. But will keep it, its history. :-)

The new controller is based on the Steam Deck controls and vastly superior to me (if we assume its like that). I can’t imagine you don’t liking it as much as the old controller.
