Pop'n Controller Compact for PS ps2, Clear Color Compared to the Pop'n Controller 2, the buttons are flatter, so this one has a wider effective pressing area and can be pressed with less force. There is some fading. Although the structure makes it difficult for dust to enter, the interior has been opened for cleaning and maintenance (to prevent the contact rubber and circuit board from adhering and making the buttons unpressable). There are multiple units in stock, so please comment if you would like one.
