Most Helpful Customer Reviews
I needed to determine which of my black wires was line vs load and this made it fast and easy. It also kept me from a good jolt when I thought I had all the electricity turned off but forgot one of the three switches in this box was a three-way and apparently on two different breakers. With a gazillion wires in this box it was still easy to figure out which of my lines was load vs line. Very straightforward and exactly what I needed. It'll get a lot of use.
Promises, promises. That's what this product's advertising touts. But fully 30% of its readings are false. Not a dependable or accurate testing device. I use my old G-B tester, which is more accurate.
I am an electrician so I use this item every day. I do not like that it must be turned on to work. And it turns itself off, so I must be very careful when using it to determine if there is no voltage, or if the unit is just turned off. I previously used a fluke which is much more sensitive and a much better detector.
Added: After using this item for a few months, I no longer trust it. Even when I make sure it is turned on, I can't depend on a reliable reading. It works sometimes and refuses to work 80 percent of the time. I am very sorry I bought two of these units because I just threw both of them into the trash. I won't even give them away because I am afraid someone will get injured or worse relying on them. They are worthless junk.
I purchased another fluke.
