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

Like the lights giving the ok of connection. Found out that my 30 amp home connection plug was wired incorrectly. Got it fixed.

It works well serves the purpose. I could not close the plastic cover because of the handle at the end of my cord and mine did not come with a lock/key and lanyard as advertised, am not sure why.

It was easy

Jusr in case of a surge or wrobg pilarity. A must have when you go to an RV park and use their electricity.

The unit came shipped with an open box and had small pieces of what looked like grass inside the waterproof cover. It had some dirt marks near the plug also. I plugged it in and the lights seemed to be working. I live in Florida and we get nasty thunderstorms almost daily so I hope this will save me if needed but I’m not too sure now. It seems like I’m not the first to have this issue. Otherwise it looks like a solid surge protector. UPDATE: I used it for a few days and had some nasty storms and the weather proofing worked great. I like the product. They offered me a full refund but I’ll keep it because it’s built solid. Another update. The seller just refunded my money after saying who concerned he was about me being satisfied. I told him I wasn’t looking for a refund but he gave me one anyway! Great customer service! The unit works great so far and I would recommend this product and seller to anyone. 5 stars!

Médium

Only used it once so far but the quality of the material feel solid.

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.

Great

seems to be a pretty good product
