I tested the device using a battery box since I didn't have gum batteries. The reason for the item being junk is that it powers on, but the cassette tape playback doesn't work. The radio function worked. The operation buttons responded normally. The remote control also worked normally. This listing includes the main unit, the original remote control, earphones, and the battery box.
