While the equipment is old, it's in pretty good condition with no noticeable dirt or scratches. CDs load without issue, and all switches and functions work. Outputs are fine, and it operates well. The only flaw is that the black handle on the right fader is a bit sticky, but it's still perfectly usable. I used it for solo play, loading CDs and applying effects. The unit might be a bit heavy, but it's perfect for those who want to enjoy music beyond just listening! (Of course, those who want to use it as a CDJ are also welcome.) 【Product Description】 The DENON DN-S3500 is a high-performance CDJ with reverse playback and loop functions. - Model: DN-S3500 - Display: Backlit LCD - Brand: DENON - Features: Reverse playback, brake, loop function - Controls: Pitch control, hot start - Connection terminals: USB port - Operation buttons: Various operation buttons Thank you for viewing.
