Product review (5 stars): AMAZING SILICONE COVER
This product is amazing!  It's large enough to cover the top of a 9x13 inch baking dish.  I no longer will have to cover these dishes with aluminum foil (no waste).  What makes this product amazing is the fact that it seals around the edges of the dish and you have to lift the little tab to break the seal.  Because of this, the food stays moist and doesn't dry out. I was afraid the cover might melt when I put it in the oven, but it didn't!  I may have to order more of these because they would make a great wedding gift!
