The Pioneer CDJ-100S is a digital DJ device equipped with JET, ZIP, and WAH effects, and allows for precise tempo adjustment. - Model Name: CDJ-100S - Brand: Pioneer - Digital Player: Digital DJ Equipment - Functions: JET, ZIP, WAH, TEMPO - Operation Buttons: SEARCH, CUE, PLAY/PAUSE, EJECT - Tempo Adjustment: MASTER TEMPO The CD ejects even when a disc is inserted. This is considered junk. The exterior is in a clean condition. However, there is a small, inconspicuous scratch on the front left corner (see photo 5). Thank you for viewing.
