easy to use, and used more than I thought would

Easy to use and peace of mind perfect

Used with my motorhone.

Havent had a chance to use this yet - pretty straightforward to use the product itself (minimal instructions - plug it into the shore power, ensure the lights indicate good power, turn off the breaker, plug in the RV power, turn on the breaker - easy enough). But there are some accessories included with zero instructions. There is a large, thin gauge plastic bag - presumably to put over the post where the shore power is mounted?? Thin gauge plastic might last 1-2 storms if you really needed it. And there is a soft cloth included, too. No idea what thats for - maybe to dry off the shore power post before plugging in ?? Just guessing here. Actual instructions would be helpful - even a scrap of paper with one sentence instructions. Too much to ask??

The product arrived quickly, but you can tell its obviously used. Plug and cable dirty and scuffed box weather cover had dirt in it. Lock and cable were shoved into bottom of box and keys were separated and rattling around the box. It appears some people recieved a yellow cleaning cloth (or something simar) with theirs ,I did not. Theres a cardboard backer with twist ties to hold the surge protector in place inside box while being shipped, nope. Not attached to it with ties. I tested the circuit with my multimeter and everything seems connected internally. And the blue surge protection light is on when plugged in. Ill update if it melts or kills my rv. Ill test it on my old hunting camper first, Im not stupid.

Price was great

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.

It was easy

Easy to install and looks great . Good to have peace of mind that everything electrical is safe .

Nice unit, I like the rain cover and lock.
