Those cookware pieces are not even close to the heavy stainless quality of All Clad. That's why there's a huge difference in price--and weight.
All Clad is heavy multi-ply steel on both the bottom and up the sides. Many other brands are heavy only on the bottom and have thin stainless on the sides.
I ordered a Puck cookware set about 7 years ago.........arrived with rust in some of the pans which was obvious when I opened the box. Very unusual for quality stainless steel, I thought. Back it went as soon as I could send it.
Sorry to sound so negative about an otherwise respected product and vendor, but that is my opinion and experience only.
