Bests & Worsts Reviews from Amazon

I purchased this Electrical Management System (EMS) back during the winter. I've used it every time we went camping. Two weeks ago I was at a State Park in Michigan and the (EMS) shut everything down. I was like what the heck! Then I thought, oh the (EMS) is doing it's job. I went to check to see what the error code was and it read low voltage was detected. Two minutes later every thing in the trailer kicked back on. I must stress!!!! If you camp and plug in, you must have this! I just got my Trailer last October. I would've been pretty upset if my electrical equipment have gotten fried! Also, the product is American made in North Carolina.
