I bought more stoves in different diameters of the mineral series B. These stoves are slightly more expensive than Teflon, but so much more healthy and sustainable! In addition, the dishes we prepare there are much better, the meat remains soft at heart and well captured surface. By following the care instructions, you have them for life in your kitchen. The system with removable handle is very convenient, stacked one on top of its stoves others, so needs less space for storage. The system is very safe, effective, the handle is never hot. It is true that they are heavier than other pans, but more solid, effective and sustainable! I am delighted with my purchases.
