I have a similar Concord LeisureMan set and have been very content with using them in the past year or so. I also own a Tri-ply Calphalon set. This Concord set does almost as well as the Calphalon. For its price, it's worth getting it if you're on a budget but want to own a cookware set of decent quality. As for the stains that some of you mentioned, if they resemble blue-ish/purple-ish watermaks, I believe that it's a reaction from the stainless steel (SS) with certtain food/liquid. I use a plastic scouring pad such as the Dobie by Scotch Guard, and a little of the Bar Keepers Friend to wash it off. It brings back to its original bright look. No hard scrubbing is needed. In a matter of fact, you can use Bar Keepers Friend with any item that is SS such as pots, pans, sink, etc.If you're new with using SS pots/pans, here are some suggestions to prevent food from sticking to the cookware: 1) Preheat the cookware first. Start with a low heat level for a minute or two before turning it to the desire heat level. 2) Avoid putting cold or frozen food in a hot SS pot/pan. 3) Avoid using Pam spray, (leave spots that won't come off). It's best to use oil or butter when need to. If food sticks, soak the cookware in warm water for a little while before washing it. Avoid scrubbing hard with your tri-ply cookware and avoid using a steel wool to wash them. Hope these tips help you.
