I dislike it. was trying to plug in the yard then I noticed its not long enough. still need another extension. not sure its safe from the built.

No issues, works great!

Easy to use. Great value

Took it out for this last camping trip worked great easy to plug in and unplug at the end of the trip.

Cover doesn’t shut all the way, needs to be bigger with the added grip loops on the plug in. Water could get in, used it in a torrential downpour and didn’t have an issue. Light diagram is simple to understand. Surge protector is a must have if you don’t want an unexpected repair

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 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!

Inexpensive insurance— you never know what kind of power you are going to end up w/at some campgrounds. I would rather blow a $60 part then all of my control boards in my camper.

It works for our 30amp RV.

a good thing for the rv that works well
