Lakeland PushPan Loose Based 23cm Cake Tin - Round 5 "A good range that works for me" Vanessa Parrott 25 June 2020 I bought my first PushPan tin a few years ago, found my cakes got better and replaced nearly all of them for PushPans and haven't regretted it. I never noticed (or perhaps disregarded) the instruction that they don't need lining. I wouldn't bake a cake without lining the bottom and that is how I have proceeded with PushPans. The sides don't need lining. I have also never had the problems reported by others with the bottom edge of the cake. It's true you need to clean the silicone seal carefully but that's no big deal. And you need to be careful with the angle when pushing the cake out.
