Pots have long been in use and still provide satisfactory us. Handles are only slightly warm, knob from the lid, however, very hot. The lid close well and do not rattle. The pots are used on induction and are thus very quickly to operating temperature. 1 liter of water boil in less than 2 min. Pots can be easily cleaned only slight streaking inside when cleaning with dishwasher. Would I buy it again.
