We bought one several years back. We stay in an old park in Colorado. We had some bad winds earlier, and a tree came down on a line. Over the course of several days are electric would go off and come back on. Then one day while running 1 A/C which all that can be used up here, as its 30 amp park, You could hear things kick off and then try to come back on. I was glad I had the protection. Not sure it would have taken out anything but I felt good that I had the protection. We stay here for 3 months, so this is a good investment. If I trade again, I'll make sure I get one that is hard wired.
