I bought the 12"x12"x4" multi size pan. In theory it sound great, One pan that folds up and can be used for various sized cakes. Unhappy with the construction, the lip on the base is not high enough up to give support to the whole structure when making larger cakes. I found it quite difficult when taking it out of the oven. My daughter tried it too and had the same problem (an accident waiting to happen). The "teeth" that allow the internal sections and the corners to slot into each other are made of a material that bends very easily so if you get any cake batter on the tin you cannot put any pressure on these to remove it, you just have to soak well and hope for the best. I was also surprised that the pan is not dishwasher safe. Don't know if this helps, or if it was even the pan you were going for. As for purchasing the multi round tins, I have had excellent results with a baking tray and cooking rings, lined of course, and the cooking rings have many more functions.
Thanks for responding.
Thank you for the response Gales. No one has responded regarding the mini rounds, hexagons or squares. I can tell you that I have used these with much success. If anyone else has used them, I would like to hear your response as well. Alan
Thanks for your comments Alan, the idea of the pans is a brilliant concept, I just wish the lip was a fraction deeper on the sides and the teeth sections were of a less bendable material on the square tins. I forgot to mention I have several of the loose bottom base pans by Silverwood and they are super. Love their 4" round "pork pie" style, these tins are in use a great deal at the moment as I am finding lots of people want a smaller christmas cake for elderly parents, relatives or just for themselves.
Just had a thought. I wonder if these square pans have been tried out in different levels of oven? I would think that people using ovens at eye level would not have the same problems myself and my daughter had. We both have ovens that you have to bend down to get items out of and it is therefore not as easy to ensure your grip is on the base of the pan and not the sides.
