This is an MD recorder made by SONY. It has some scratches on the surface due to being stored at home. There is a crack in the LCD screen. I have confirmed playback and button response using my own adapter, and all functions seem to be working. I have also confirmed recording using my own microphone, so I believe it can be used without any problems. In the unlikely event that it does not work, I will offer a refund. This unit does not support MDLP. Shipping will be via Takkyubin Compact. Discounts are available for combined purchases with other items! Please feel free to comment.
