Valve has started contacting individuals on the Steam Controller waitlist by sending reservation emails to finalize purchases. Recipients have until May 18 to confirm their orders, or their reservations will be canceled. The first batch of controllers began arriving this week after the reservation system launched on May 8, following the controller's sellout in 30 minutes on May 4. Those with reservations should check their email and spam folder, as Valve is not sending reminder messages. The purchase window is 72 hours from when the email is received. Fulfillment will start in the United States and Canada, followed by the UK, Europe, and Australia. The reservation system does not strictly follow chronological order for email distribution. Users not included in the current wave of reservations will remain in line for future batches, though Valve has not announced when these will be dispatched. Resale prices for the Steam Controller on platforms like eBay are significantly higher than the retail price, despite anti-scalper measures in place. The Steam Controller features TMR magnetic thumbsticks, dual trackpads, gyro support, four rear grip buttons, and a Puck accessory that functions as a charger and 2.4GHz wireless receiver.
