Considering their price point, I'm sure you could get 2-3 replacement sets and they're still making a profit. Going above and beyond their warranty a few months just helps them with future sales.
I bought these back in August, WAY brighter than stock, no errors, etc etc and have them in my E70 X5M as well as the GF's E61 535xiT. I accidentally bought two full sets, so on the chance these go out, I've got an extra set for each car.

Unfortunately our angel eye rings design sucks, which can even be seen in Lux's photo's, to where the inner is always going to be brighter than the outer...unless you stand in the perfect spot and even then you'll still see it -
