Manufacturing Years: 2009, 2011. Functionality confirmed. Both units were overhauled by Pioneer in July 2020, with some parts like the play and cue buttons replaced with new ones. No issues with buttons, contacts, or displays. They have been used for several years, so there may be some minor scratches. Accessories include only the power cables. The original boxes are not available, so they will be packed in a different box. Functionality has been confirmed, but these are older units, so please refrain from purchasing if you are extremely sensitive or have no understanding of used items. Power cable only included (non-genuine). Pioneer CDJ-2000
