The ceramic sockets aren't cheap Chinese ones, they are genuine NOS Soviet production from 70s, with totally different clamp system which provides much better contact and reliability.

A great cooking set for just about any meal.
Size: 11-Piece Set
This is a great set of cookware at a very reasonable price. I was looking to make the switch from using non-stick coating to something more natural to minimize the risk of potential toxins. This stainless steel cook set comes with everything that you need to cook just about any meal. As with any stainless cook set, it does require a different approach to cooking, but it's a good tradeoff to know that you're using steel instead of non-stick coating. The quality feels very sturdy, and I feel like these will last me a long time. They are very easy to clean if you soak and use something like bar keeper's friend for anything that is stuck.

Everyday use
Size: 11-Piece Set
I've used these pans for about a year now and they are still holding up great. For everyday abuse they do not faulter. Plus they clean easy. These pans are a great way to get name brand quality without breaking the bank.

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.
