Great device to have so you wont blow your RVs Converter

Great tool to have.

Seems well built

We own a RV Park and my wife was not good at using a multi meter so I ordered this for her. She loves it.

So far, this little gadget detects bad circuits. Could save you lots of $$ if you happen upon a bad plug.

Easy to use.

I pull into a campsite, plug this in, if it tells me everything is ok I plug in my 50 amp cord. I have a built in

This little device saves us from disaster!

Seems to be a well built tester that feels solid. Worked great to test the pedestals in this campground.

These work well just plug them in and know if the power pole is set up correctly. And if there is an outage in the RV they help you locate if it is inside or outside for quick Diagnoses...
