this unit comes in its original packaging with the instruction manual. The clip in the battery compartment was corroded, and I’ve removed it. The compartment that the clip goes into appears to be in relatively good condition. I have not tested or done anything else to this at this time. it is being sold as is. Be sure and check out all the pictures as they are critical part of the description. Typically ships in 24 hours or less excluding weekends and holidays.
