Solid design, long lasting, healthy surface for cooking
Size: 11-Piece Set
I bought this exact set in 2021. I am buying more. With the number of reports about the dangers of pans made with non stick coating I decided i would only use cast iron or stainless steel going forward. These are “amazon brand” but I can say after years of use and abuse they are standing the test of time. Multiple moves, toddlers, rough use and they are all fully functional and work great. I LOVE the teardrop handles. It makes it so easy to hold the handle and the hanging holes on the handles are large allowing you to hang it more places on more things you may already have set up in your kitchen. I think anyone who is looking to get away from cheap, chemically pans off the rack should look at this set!! I have 4 years of proof they are not junk but a great long lasting items that seem to be well made. Higher price than buying a $10 pan at walmart but you get so many pots and pans with lids that will last a lifetime. You can also use stainless steel to cook in the oven so more functionality than most pans and pots you buy of the rack. You will just need to learn how to cook with stainless steel pans (check YouTube lots of instruction there).

Very pretty cookware
Size: 11-Piece Set
This is nice quality cookware for a great price. I have seen cooking shows that tell how to cook in stainless steel without it sticking. Unfortunately, my food still sticks. If I use a lot of oil, it isn’t so bad. One cooking show host says if you get it real hot before you add the oil, it won’t stick. It sticks. I am trying to get away from using Teflon because they say we have a lot of Teflon in our bodies from our cookware. I still go back to my Teflon a lot. But the cookware is very pretty, a nice weight, and cleans up fairly easily. I do soak the skillet before I clean it. I don’t have to do a lot of scrubbing. The sauce pans are great.

Cooks well, cleans easily
Size: 15-Piece Set
Bought this to replace old nonstick cookware. Looks good and not too heavy. Pot handles are cool enough to hold near the ends but tend to warm up close to the pot itself. Using on a gas range – heat spreads quickly and cooks. Best on low heat. Some sticking problems with food like cereal, lower heat advised. Glass lids are very handy with steam outlet. Have not used all of them yet, but they store and stack easily and I was looking for a good size stock pot and this should suffice. Not as heavy as other stainless steel cookware. Price reasonable for the number of pieces included.So far I am very pleased with this purchase.

Heat up well before use for "non-stick".
Size: 11-Piece Set
I really l Iike these stainless steel pots. I had to learn the trick to using them, and that is to make sure they are heated up properly before using. This makes them "non-stick" and your food won't stick to the bottom of the pot, especially if you're frying it. Also follow the manufacturers instructions and "season" the pots after you receive them, by coating the insides with oil and heat them up. They cook really well, are light weight, easy to use, easy to clean, very sturdy, shiny surface, and holds heat after you've finished cooking. Also, don't use harsh scrubbers in them because it will scratch the surface. Scotch Brite Scour Pads work well in these pots. If you scratch them, use the green Scotch Brite Scour Pads to polish the scratch marks out. Enjoy them!

EXCELLENT DEAL.
Size: 5-Piece Set
These are authentic food grade, stainless steel pots and pans sold for ten times more via other companies. I did the research and the part where we cook or boil is stainless steel. The core is aluminum (we don't get that when we eat) and the outside is stainless steel again. Beware, though, they are SUPER HEAVY. Lift weights before picking them up! We love them. Wish we'd bought them sooner. You can't cook on high with them, though, b/c it will burn the food, since it isn't nonstick. We've learned to cook low and slow. No need to scrub so much. That's the only drawback. Great quality!
