Waterless cookware is the best! I've been using it since the 70's. Stainless steel inside and out, with thick aluminum sandwiched between all the way up the sides and across the bottom. Cost me $350 for a 20 piece set 30 years ago. Terrific purchase. Use it daily and it still looks like new. I did replace the handles a few years back, but I got them for the cost of shipping.
