This little synthesiser is a clean unit and the keys are in perfect condition. The surface of the unit looks to have very little wear and all the buttons and knobs seem to work great. I do not have a user manual but they are easily available on the net. This instrument does come with its original hard shell case also in very good to excellent condition and a replacement 9 Volt power adapter is also included. There is no stand included. This little synthesizer has a clean sound with no crackling in the faders and everything works very nicely.
