Query: So glad we bought this set

We purchased this set about a year ago and absolutely love it. It did take a little getting used to how quickly it heats the food. We have learned to cook on lower heat. Clean up is easy. You have to give it the vinegar treatment every once in awhile to shine it up again, but that is not a big deal. We replaced some Teflon coated cookware and was worried about sticking. Again, you learn from some trial and error, but we have gotten it down pretty well. We have since purchased additional pieces. Only problem, my wife put on veggies to steam...forgot to add water! Ruined the pan - not the pans fault. So I am out to purchase another piece to replace it.
