Are all these sets induction-compatible?

Yes — every set in this roundup is marketed as induction-ready, including the Cuisinart MultiClad Pro, T-Fal Ultimate Hard Anodized, All-Clad HA1, HexClad Hybrid, and Amazon Basics stainless. That said, induction performance depends on base flatness and magnetic content, and full tri-ply stainless (like the MultiClad Pro) tends to get the strongest induction reviews from testers.
