Review on Yellow RV Surge Protector 30 Amp - Briidea Adapter Circuit Analyzer with LED Indicator Light, 30 Amp Male to 30 Amp Female for RV Trailer by Gunaraj Varga

That sucks! First, it's difficult to connect. Second, I plugged it in and it said everything was fine, so I plugged in the cord for my camper. It was very difficult to get in, but eventually it worked. It's been fine for a few days (this is our first time we've used it (less than a week). We were going camping yesterday and the power went out in the camper, so all brakes aside, no it is fine but won't turn on so we get out of the outer box and open it, pull it out and it melted in the stupid surge protector, it ruined the cord and outlet we were plugged into so we had to use it replace all so DO NOT BUY THIS THING, I UNDERSTAND IT'S CHEAP BUT IT WILL DO MORE DAMAGE THAN WORTH ITS COST, save yourself the trouble and listen to me learn from my mistakes, don't buy this thing !
