Nintendo Pro Controller with Splatoon 3 design, supports wireless connection, and features a comfortable ergonomic design. Thank you for viewing. [Maintenance Record] Due to the aging of the stick sensors, malfunctions can occur. Therefore, I have disassembled the controller to remove dust, cleaned with ethanol, and applied contact cleaner. I have also checked the condition of the buttons and cleaned them. (I have a past record of creating and selling custom controllers, and I have performed these tasks accurately and reliably.) [Operation Check] I have confirmed the following operations: - Button press check - Stick sensor check - Vibration check - Gyro sensor calibration - Firmware updated - Charging and LED illumination during charging - Connection to the main unit and Ch1~4 LED illumination [Notes] There may be minor scratches near the charging port, although they are not very noticeable. Please check the photos and understand this beforehand. [Cancellations and Returns] Returns are accepted for operational defects reported within one week. However, you will be responsible for the return shipping costs. Cancellations and returns due to other reasons are not accepted.
