My personal description. How much was this unit used? I've used this unit for 7 months total, 2 to 3 days a week for 3 hours at most, and it's never left my studio. Condition. This unit is in excellent condition. Almost like new. Flaws if any. If you look closely enough at the unit, there is some slight cosmetic wear from normal use. There's also a small nick on the front of the unit that was there when I purchased it. I had it checked, and the nick turned out to be from the manufacturing process. However, the cosmetic wear and the nick is so slight and small enough that I don't think that it shows in the pictures. These miner flaws do not effect use/performance. Where is this unit stored? This unit is stored in a pet free, smoke free environment, and has been cleaned thoroughly. Was this unit tested? Yes. All knobs, platters, faders, switches, buttons, pads, sliders, touch strips, VU meters and ports/connections have been tested and work properly. What's in the box? Numark NS7II dj system. IEC Power cable. USB cable. Allen wrench. Why aren't any drivers/software disks or users manuals included? All of the updated drivers, software and users manuals can be found on the numark websight.
