A Casio CTK-120 in excellent cosmetic condition. No AC adaptor with it but it works with batteries - although I'm not sure it is working correctly. All the buttons/keys work but the sound seems off - the louder you turn the volume, the worse the sound becomes. Please see my video for a full description of this issue. It may be that my batteries are running low but sold for spares repairs just in case. Thank you,
