Cooking is extremely time I said, but with this type of container, preparing several meals at once, it goes beyond my expectations, it's a great energy gain also, it is cheaper on our wallet, and also on the door leaf on the planet, we must think about from time to time ... enough to prepare balanced meals in advance, only to prepare animal protein (for carnivores only ;-) ) and voila. In short, excellent quality of stainless steel, which is not yet stamped 18/10, but no doubt this material will take a while, it's a good product that is worth its price, for my part I ' have been around, I validate the product as quality (and I'm picky about food materials). Merry Christmas: o)
