I haven't had much chance to use this since I bought it used, and it's been kept in its case. The response of each switch and pad, as well as the touch screen, is working without any problems. There is no stickiness on the pads. A protective film is applied to the touch screen. An AnalogCases dedicated case (this alone costs about ¥10,000) is included. I stored the adapter along with the unit by removing a part of the sponge, as shown in the last photo. Included are the main unit, the dedicated case, and the power adapter. There is no original box, so it will be shipped in the case, wrapped in bubble wrap, etc.
