I love a lot about these pans. However, I have only used them to bake cheesecakes, so I can't say more about them than my use for making them. The cakes slid out cleanly the first couple of uses, but then need a little bit of help from some non-stick cooking spray to come out nice and neat. This is not a big deal to me. Also, I highly recommend purchasing some 2.5" parchment square circles if you will be doing a decent amount of baking in these pans. Cakes slide off okay, but they slide off the discs MUCH easier with parchment circles. The discs can be a bit of a pain to clean because the only obvious way to clean them is one at a time. If someone comes up with a faster way, please let me know!!I have had problems in the past with this type of pan rusting. I have had these for about 5 months now and I have not had any issues. All-in-all, this was a great buy and I would highly recommend this pan for mini, pretty desserts.
