Review on Southwire M500CX4 Coax Continuity Tester/Mapper: Durable Design, Auto Power-Off, LED Display & 4 Color-Coded Remotes by Balthazar Cooper

My house was connected to 3 different coax groups (satellite, cable, CCTV) but not very well marked. This tool made it easy to keep track of which wires were connected to which outlets on the basement electrical panel, and particularly to keep track of which of the multiple wires went where in the junction box in front of the house. Connectors you want to trace, then go to the other end of the cable and connect each cable until a green light comes on next to one of the colored dots and you have identified those 4 connectors. Repeat until everything is identified and you're done - it couldn't be easier. I took off a star because the color coded "caps" are stored in a piece of foam that is separate from the tool itself, which is almost guaranteed to hit. eventually split up. If the manufacturer had provided storage space for caps in the body of the instrument, it would easily have gotten 5 stars, even if it had cost a few euros more.
