Review on 🔌 Southwire Data Coax Continuity Tester, M550 by Tony Pierce

Bought this tool to install a 4k HD video system. While connecting the wires I kept getting bad readings. As a beginner I cut off the ends and tried again, same problem. Getting down to business, I tested before making the final connection to the recorder and to my surprise I found an error. Stunned by the second results, I borrowed one from a friend and tested it again. Guess nothing wrong. Finished work. At this point I would not recommend this tool.
