This line of stainless steel stock pots combines great quality and remarkable value. The wall thickness and overall mass of the kettles is significantly higher than economy kettles. The 5 mm-thick bottom has three layers - an aluminum layer sandwiched between two stainless steel layers for superior heat dissipation. All MegaPots come with a heavy-duty stainless lid and hollow handles. To prevent damage during shipping, A and B model MegaPots require minimal assembly that can be done with a wrench.
