There isn't anything I don't like about this product yet but what I do like is the ease of use and the different types of testing on this product. When dealing with traffic light devices, they can react somewhat sensitively to overvoltages and lightning. Proper wiring is critical to saving or destroying your equipment. The test I performed was a continuity test using a shielded CAT6 cable for direct burial, the ground wire should not be connected on the equipment side but on the power side as you can see in the picture, this will show that my connection is correct and one side faces the ground. I love this tester and I love the price I would recommend this product.
