Used, in good cosmetic condition. We have tested this unit to power up and found that the little tube has a pinch in it (shown in photos) and will need to be fixed or replaced. We were able to put a charge on the battery and it seems to be holding but the battery may still need to be replaced.
Unfortunately we do not have a power supply we can include to charge the battery. There is a case included in the listing. This unit may need to be calibrated.
