Anyone tried one of these HEI Distributors?

I don't automatically discount a product just because it comes from China. The easy example in electronics is all the Apple products made there. So junky I phones, I pads, macbooks too I guess. At this price and with people here running them trouble free I don't see how it fits into the junk category. Lower quality maybe but we are talking less then 1/5 the price of a mopar performance electronic conversion. I'm willing to take those odds anyday!
