M1A2 New Generation RV Surge Protector 30 Amp 50 Amp with Waterproof Cover Camper Anti-Theft Circuit Analyzer Tester Plug with UL Tested

Works just as advertised

Item arrived on schedule and does what it advertises however the packaging was in bad shape and the item had clearly been opened previously and likely returned. Because it does what I need I dont really care what I would have given it a higher rating if it arrived in new condition as advertised.

Very easy to use. Directions are very clear. Indicator lights are easy to read. Works great!

this gives me peace of mind when i am at different campgrounds. it also helps my camper connect better to the electrical than if we hook it up without it.

Works as described

When first connected circuit protector showed correct wiring and ground for a few seconds. Then showed open ground after that. Park maintenance replaced 30 amp circuit breaker. Their test showed power was correct and properly grounded. I tested a 120V outlet inside my camper and it showed correct wiring and ground. Next morning this device showed circuit was correctly wired. How do I trust this device will show correct circuit analysis during each future use? I cant so returned.

This works exactly like a standard outlet polarity/ground checker, with the added benefit that it provides surge protection and that it is in line with your power source. Installation of this is quite simple, just plug this into the power source you will be using for your trailer/RV, read the lights to determine if there are any issues with the electrical, then plug in your RV/trailer power electrical cord into the device of all is ok, at which point you are also getting surge protection. It comes with a lock/cable to secure the device but I frankly dont see the value in it. If someone is going to get close enough to steal this from my trailer/RV, the lock/wire will not be enough of a deterrent, in my opinion. One item that was a bit of a mystery to me is that it came with a large clear plastic bag, not entirely sure what this was for since no instructions are included beyond whats on the sticker of the plug, and box.

There is another photo evidenced 2-star review from another purchaser. I’m sure this review will get buried but this randomly happened during my parents 3-week stay at a lake RV resort. Circuit analyzer melted where my parents RV power cord connected into the analyzer. The resort’s power plug was fine and so was the top plug of the analyzer as evidenced with photos. Did not cut the power when there was an obvious abnormality in the voltage resulting in a burn that ruined the analyzer and parent’s RV power cord. So I do not recommend it for reliability.

It was good item an works as it says
