The failure rate of the OEM bearing in the first 3 years/30k miles is probably far less than 1 in 10,000. And pretty much all of the existing LN bearings are in that category. So I would be surprised if any had failed.
I can appreciate their admission that the longevity of the bearing cannot be determined experimentally in the lab without better equipment than they have. This is exactly why critical car parts aren't made by small shops. And it is also exactly why car manufacturers put their critical parts through rigorous testing.
Ceramic is a great material for bearings but I seriously question about how long it will last with only splash lubrication.
