Yes, they should. But they won't. Not in any significant numbers anyway. People seem content to live with faults for some reason. They let CGC off the hook like they are a group of children who are 'doing their best'. Ahh. Look at the nasty people criticising our CGC.
I agree, the fix is likely to be difficult, time consuming and costly. The predisposition to rings was either not picked up in development, which is at best clumsy, or it was and a conscious decision was taken to 'justify' them to avoid a financial hit. It's that part that I dislike. The clear attempt to persuade people it was ok to have Rings - normal. And the reluctance to accept returns. The self imposed severity levels. You pay return shipping. Must report in two weeks. Etc.
There's a picture of them all sitting proudly under the heading "5 million items graded", looking like fine upstanding people. I'm sure they are.
Problems happen. It's how companies deal with them that defines them.
That sounded like a Batman line!
