Green Wheel bearing help

"They are absolutely nowhere near as durable as the factory style tapered bearings manufactured by the TIMKEN corporation. They will never last 100,000 miles like the Timkens. They will not last if you enjoy road racing or any type of cornering"

This is so ridiculous I can't stand that stuff like this gets on the board and people believe it.

I've been road racing with these for years without issue. Besides if a ball bearing is good enough for every performance car in the world pretty much (including Corvettes), (they road race too I think), why aren't they good enough for guys with specialty cars?
