### ⭐⭐⭐⭐⭐ The right tool for the right job.

### ⭐⭐⭐⭐⭐ Reliable, Accurate, and Built for the Job

### ⭐⭐⭐⭐⭐ Cheap, reliable and simple. Love it.
*by S***Y on December 3, 2019*

I've been using these at work and love them. Light weight, simple to use and reliable. This will not get down to the finer details of measuring resistance readings but will tell you where the weak spots are in a circuit. The lower cutoff point on this meter's scale is 20 Megaohms, well above levels I have seen circuits operating without tripping overloads or breakers. All of the problem circuits I've diagnosed with my expensive Fluke megger have shown less than 1 Megaohm from conductor to ground. I still love this meter, though, because it is so light and compact. I also like that I can attach the alligator clips and leave one hand free to wiggle wires in the conduit on intermittent problems while I press the test button with the other. I have thus far not misdiagnosed a motor with this meter but I usually go get my Fluke 1507 if I am in doubt. You will love this megger.
