Review on 🔌 Southwire Data Coax Continuity Tester, M550 by Edgar Clark

I have used this solely for testing new CAT6 runs and it works great and is extremely easy to use. Saved me time fixing keystone not working properly on my first project after receiving the tool. The diagnostic lights are easy enough to figure out without resorting to three glitches. If you don't want a fancy, expensive tester with all the bells and whistles you'll never use, but cheap models scare you, then THIS is what fills that gap and it's what you're looking for!
