I purchased this item from someone a few years back. I barely used it, I purely bought it on pure hype a few years back. It has signs of usage, dust and a little wear from previous users, but it comes with majority of the upgrades (outputs, soundcard, and SD slot) however it does not have the OS upgrade with the bluescreen. Also the note variation knob is hyper sensitive. So when you're using it, you barely need to touch it. I'm not sure if that is an artifact or that is just how it works. The bottom was opened from the customizations of whoever owned it before me and I think they used their own screws to enclose the bottom. But honestly for its age it is in very good condition, no major damage or wear and tear! I personally have no use for it and already have 4 other MPCS lol.
