Purchased for 30,480 yen on the void gaming official website. Even considering it will be cleaned up and returned for a repair cost of about 5,000 yen, I think it's cheap. See image 4 for details. The faulty part is in image 5 (the black area doesn't work). Other than that, it works fine, but it will be treated as junk. Remapping available, two back buttons, no vibration function, mouse. The warranty has expired, so please refer to image 6 for repairs.
