In the last two months I received back 11 books. Only in one I can observe newton rings. Not big deal.

That is about 9% failure. Would you accept 9% failure from a new automobile, or a new furnace or a prescription? Maybe not equal comparisons, I know, but it is a respected business with a continuing history of the same failure consistently. In that regard, it is a big deal to a lot of the customers.
