This is a very heavy gauge bread tin, which will not warp in the high oven temperatures required in bread making. The bottom is narrower than other makes which means that the bread doesn't spread out and the high sides mean that you get the taller slices for bread, which you don't get in a loaf tin which is really designed for cakes. Overall, I'm really very impressed with my purchase (and the supplier), so I would gladly recommend this to any other bread maker.
