WELLUCK 50 AMP RV Circuit Analyzer, 50A 125V/250V RV Pedestal Tester with LED Indicator Light 14-50P 50 amp Tester Plug for RV Camper, Travel Trailers (ETL Certified)

Seems well built

This little device saves us from disaster!

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

Easy to use.

worked as advertised. My electrician even used it after WallBox blamed my 240V outlet for their faulty product based on a ground disconnect. I think he decided not to charge me for the follow up visit after using my Welluck circuit analyzer.

Great device to have so you wont blow your RVs Converter

Great tool to have.

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...

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.

Bought this device to check electrical hook ups at campgrounds before plugging in my camper. Works great and tells me if the power is okay before I plug in.
