Quoted from KenLayton:There is a bad batch from Pinball Life floating around. An operator friend had some of those rubbers and they were all breaking within a week!
He now buys all his rubbers from Marco instead.
Were they white? I suddenly have my white ones torn up in a very short time. Especially the ones on the posts. I have been getting all mine from Pinball Life. I have no way of telling the new batch from the old though.
