We perform full cleaning, including button rubber and circuit board cleaning. We have tested all functions, including software loading and the touch panel. The tact switches for the LR buttons have been resoldered with new ones, providing a crisp clicking feel (most used original DS units have tact switches that are worn out, resulting in almost no tactile feedback). The exterior and touch panel have some minor scratches. The top and bottom LCD screens are in excellent condition with almost no screen burn. Touch pen included. - Model: DS Lite - Screen: Dual Screen - Condition: Good condition Thank you for viewing.
