Review on Sperry Instruments TT64202 Cable Test Plus - Short, Miss-wire & Reversal Detection - 2 Pc. Kit by Kevin Mitchell

We were renovating our house so I did 12 cat 6 runs around the house and some to 100 feet. After crimping the RJ45 I used Sperry testers to check the wiring and they worked great. I only had 1 failed run found by the Sperry tester. I had 1 brown wire that turned out to be a bit short so the Sperry tester showed poor contact on LED 7-8. It worked exactly as advertised. I tested it on a couple of coax runs and it worked there too. Definitely worth your money.
