I have confirmed the operation. CD, MD, and radio all work without any problems. The remote control also works. However, some older MDs may produce an error. There is no instruction manual. The white parts show some discoloration due to aging. Batteries are not included. The reason for listing this as junk is because there is only one problem: The power turns on automatically after 1-2 minutes after being turned off. Therefore, it is recommended to use an external power strip when using this. Thank you.
