Thank you for viewing. I purchased this item new and used it for about two years. Operation has been confirmed. In addition to the main unit, the original box, included cables, and dongle are included. *The sole has been replaced from the original to a product called "Oni Aim" (Demon Aim). The reason for the "as-is" condition is that when scrolling upwards, sometimes the input goes in the opposite direction. There are also instances of the reverse. This is likely due to poor contact caused by dust accumulating near the contacts. Therefore, we recommend that those who have the knowledge and skills to disassemble and clean it themselves purchase this item. *In my personal opinion, I didn't feel any particular inconvenience during normal use. We are waiting for purchases from those who understand no claims/no returns. Thank you very much.
