I'm very happy that it showed up because it's identical to the napa ones that are remanned, but this is brand new and much better on the cost side of things. I installed this in about 1.5 hours with minimal tools, it was very simple to do in my 14' silverado 1500. It was also 20 amps bigger than the stock one that died. I've been extremely happy with this, between pulling campers, 4 wheelers, trailers etc. I've never had a loss of power. This has been installed in my truck for about 4 months now and I have no complaints - it has held up awesome.
