I now have almost all of the Wilton Performance Pan sets and have purchased a "second or third" of the most used sizes. The round pan set is used more than the others. The Wilton brand is the best. I use the Cake Release, also a Wilton product, for all my layers. The finished product comes out of the pan easily and with very few crumbs. The pans do not rust or become discolored and are so easy to wash up. I have had these pans for over 3 years and use some of them almost daily and they still look as good as when I purchased them. As to the cost, they are the most reasonably priced. So for quality and cost, I highly recommend them. I love all Wilton products.
