LOL, you don't know what you're talking about. You've obviously never opened an e-core. It's a "felt" like material. Furthest thing from cardboard, and nothing like the end cap used by FRAM. FRAM also uses a much better bonding glue. I dare you to tear off the end cap on a orange can and see how easy it is. The e-cores have always been a bad design, the lack of glue is just one reason.
