as far as the reliability goes, it's been great. the cables are sloppy and cant get them just right, but that might be in my controls. takes a long time to defog when on defroster, not sure why, but other than that it cools just fine. i wish it had outside air capability, but you can just use the drivers side air vent. i'm running mine with a stock magnum a/c pump, so can't comment on the supplied sanden pump.
