Description: This is a Nintendo Switch Pro Controller in black with the outer shell replaced with a chrome gold eXtremeRate shell. The surface is shiny and glossy, giving it a luxurious look. The outer shell and sticks are new. The buttons, internal circuit board, battery, etc., have been reused after confirming they are in good working order. This listing is for the Pro Controller itself only. It can be used with both the Switch and Switch 2. Customization and Maintenance Details: The Pro Controller (HAC-013) has been upgraded with a new shell and new sticks. Since stick sensors may malfunction due to aging, the shell replacement includes dust removal, ethanol cleaning, and the application of contact cleaner. Buttons and packing materials have also been checked and cleaned. In addition, the shell color displayed on the Switch screen has been updated to reflect the new color (see image 14). Operation Check: The following operations have been confirmed: - 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: While I have confirmed that the smoothness, noise, range of motion, and response delay of the buttons and sticks are not significantly different from new ones, please refrain from purchasing if you are concerned about third-party parts or are looking for a brand new product. Also, although not very noticeable, the area around the charging port has been reused and may have minor scratches, so please check the photos beforehand.
