I have this 9" round cake pan and the square cake pan and the large rectangular cake pan and 2 muffin tins by Bakers Secret and have had them for 3 years now. They are all in great shape and still cook consistently. The cakes or muffins are always cooked evenly. The only bad point is the pans are a darker grey to begin with, and I have noticed over the past years, that they have gotten darker and I have just had to lower my oven temperature 25 degrees and minimize my baking time up to 10 minutes on some items. I have purchased this Bakers Secret brand at my Dollar Store for a lot cheaper than I see at the hardware store. You really have to check around sometimes.
