I took good care of it, but it suddenly started malfunctioning during play. The symptoms are that shots from 190 yards suddenly go 300 yards, and the 7-segment display in the middle is partially missing or dimming. I thought the battery had died, so I replaced it with a new one, but the symptoms haven't improved. I don't have the skills to repair it, so I'm listing it as junk.
