I received the 3 set Zenware silicone bakeware set free in exchange for my unbiased honest opinion. This set came with 3 silicone baking pans, one that has sqares, and two muffins; mini and regular sized. They are good pans for use in the freezero or oven. They are good for portion control. The bad side to silicone baking pans are their flimsiness. It is difficult to just use these without some sort of hard item to carry them. If you carry them individually without a sheet pan under there’s a high chance of spillage and a mess being made. I just place on a metal cookie sheet. The silicone baking makes for easy releasing of the items once cooked or hardened and no sticking as could and does happen with metal pans. Though nice pans I still wish they were not so flimsy.
