except the internal workings and perhaps quality or lack there of. in reading the evaluations the writer used the same criteria on each filter which in itself starts to show trends in manufacturing.
It doesn't address the actual operating characteristics of the filter. Yeah, it's an entertaining website, but that's about it. Start showing some real numbers for filtration, various flow rates, pressures, temperatures, etc., and then color me impressed. Until then, I'm only slightly amused (that website has been around for a few years now).
