This works great, very helpful. I love the fact that it also shows you the voltage at the outlet.

Facil de usar

I liked the idea of it. However, does not work for all type of wiring. Not accurate. I have a ground yet he is telling me no ground.

voltage incorrect

Works great

Dont know about the accuracy, but very easy to read and told me what I needed to know.

Works great. Easy test voltage, wiring, and ground fault.

En mi trabajo

Works as described. 110-220 universal input with Western standard plug so you will need adapters for overseas testing. I test all hotel circuits for safety when traveling.

If you think you are having AC electrical this is handy tool to have not does it show you the voltage it also tells weather it wired correctly and if the grounding is wired correct.. I had a problem with some shop LEDs and couldnt figure out what was going on till I had this handy tool and it showed me the lights had floating ground issue which was an easy solution.
