This is the best value cookware we have ever found. It is heavy weight, even-heating and has stay cool handles. You cook on stainless steel which is non-porous and non-chemical reactive. There is a thick layer of aluminum sandwiched between two layers of stainless steel. The aluminum is what makes it even-heating and the stainless makes it dishwasher safe. If you want a great piece of cookware for a good price, this is it.
