This is not what is advertised. I have purchased this particular item before and they had 2 layers. only one layer can burst and damage the engine. I have no idea when they switched from one shift to two instead of two. I'm outraged about that! I know this is the same item that I previously ordered because I just checked my previous order and clicked the back order button. BUT the product is different. They were in my pantry and now my refund has expired. It's a chintzy product with Kenmore's name on it!
