And then, us EVers tend to "push" them beyond ratings. If a rope says "200 pound max", do you use it to safely pick up 200 lbs? Not if you're smart. But we use a "120v 400a max" controller right up to (and beyond) its ratings. Not surprisingly, it doesn't last.
That said, they seem a lot better protected than their distant ancestors, the old PMC DCC range of "shoebox" controllers from the late 1970s and early 1980s.
That's certainly true. They learned, and improved. Like people, it seems that a young company has to learn fast as a child, then somehow survive its brash risk-taking adolescent years without killing itself, before it can produce really good mature products.
