Rose:

It may well be that they haven't encountered the problem yet. One thing about JDS--they take back and replace whatever you tell them is bad.

I buy plaques by the case and sometimes I don't use all of them for quite a long time. Then I discover one is cracked. They have always replaced everything.

I also got some brass I didn't like--nothing wrong with it but it wasn't the look I wanted. They took that back with no hassle.
