Why we love this..Durable 5-layer stainless steel and aluminum base design. Delivers fast, even heating with no hot spots. Thermally efficient 5-layer stainless steel base with encapsulated aluminum disk eliminates hot spots and provides fast and even heat distribution. Non-corrosive stainless steel interior will not react or alter food's natural flavor. Tempered glass lid allows you to monitor cooking progress without letting heat and moisture escape. Riveted stainless steel handles remain cool to the touch on a cooktop.
