This is a Toshiba CD radio cassette player. There are some issues with the cassette deck operation. After playing, rewinding, or fast-forwarding and stopping, the door lock releases after a short delay (0.5 to 1.0 seconds). If you try to open the door too quickly, it may occasionally remain locked and not open. It can be restored by turning the power off and on again. This doesn't happen frequently, but I'm listing it as slightly problematic. It supports recording and playback to USB and SD. Various functions can be used with the remote control. I have confirmed the main functions, but I haven't been able to check everything. I cannot offer a warranty, but I appreciate your understanding and consideration.
