Product review (5 stars): A truly great product!
We purchased this three pack to replace a different brand oven liner which quickly deteriorated.  My wife loves to cook (lucky me!) and she uses the oven almost every day.  It has been six months since we purchased these and the first liner is still in great condition.  At this rate will be years before I need to reorder them.  They work great, and spill cleanup is accomplished with just a wipe.
