I dropped it while moving. It's generally still in relatively good condition, but there are scratches as shown in the photos due to the fall. Also, the USB receiver is missing and will not be included. When the power switch is turned on, various indicators such as the indicator lamp function normally, so in my judgment, the main unit appears to be working without any problems. This product is being offered for sale to those who understand the condition of the photos and the above contents. Thank you for looking. Thank you very much.
