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

Theres not much to say it seems to be working. Havent had any issues with it yet.

It works very good

seems to be a pretty good product

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.

The unit itself appears to be working fine although no real way to know. The little cable lock is a joke. I cut the cable with an electrical wire cutter. No big deal as I would not use it anyway.

No issues, works great!

I did not get Storage Bag

After being parked in my RV, and seeing the other people, having a surge protector in the box, I got on Amazon and found this, and I am very happy with it. The number one fear apparently would be somebody would steal it in this even comes with a padlock.

Great product. So easy to use and makes hooking the trailer up to electrical so fast and easy!

Not used yet. Very well made.
