From a hardware perspective I can tell you that the input/output wire is current limited both directions, it is microcontroller based (running at 1.2mhz), has a full automotive grade power supply, is assembled on high quality, production grade circuit boards, utilizes genuine Molex wire harnesses, and comes enclosed in a high quality plastic enclosure. We don't use any cheap parts in manufacturing these things!
