Valve Steam Controller with wireless dongle, dongle dock, and battery door. Comes with everything seen in the pictures.
Before buying, make sure you know how to connect and use this controller on your PC. Valve has (more or less) dropped support for the Steam controller on modern versions of Steam, making it an obtuse process to connect and use the controller. I don't provide support or technical help with setting up this controller. Make sure you understand this before buying.
