Tested as far as it does turn on and shows battery ok status. I do not have anything radioactive, so I am unable to test further.
The unit is in overall normal condition. Some peeling on one side. Some terminal discoloration on one of the battery connectors. Everything else appears to be normal wear for a unit such as this.
Please refer to photos and video for condition details.
Please contact me wit any questions. I will ship same or next day. Good luck!
